Definitions
- the invention relates to a plug-in device for contactless energy transfer from a primary part to a secondary part, each having at least one coil, which are inductively coupled to each other.
- the invention further relates to an operating method for safely operating such a plug-in device.
- contactless plug devices Compared with connectors in which an energy transfer via mechanically to be connected or disconnected contact elements, contactless plug devices have advantages in terms of wear due to a high number of mating cycles or strong vibrations. In addition, contact erosion during insertion or removal under electrical load is prevented. The danger of forming arcing when disconnecting plug connectors with a high current load is not given in contactless plug devices. Finally, in the contactless transmission of energy is a galvanic isolation between the primary part and the secondary part, which may be required, for example, for use in the medical field. The lack of mechanically consuming interlocking contacts also allows a design of the plug-in device with surfaces as smooth as possible, which predestined the contactless plug-in devices suitable for applications with an increased requirement for cleanliness / hygiene, for example in the food industry.
- the document DE 2 75 27 83 describes a plug-in device for transmitting electrical measuring signals, in particular in the medical field, in which an annular receiving coil is integrated in the plug, which is coupled inductively with a likewise annular transmitting coil in the mating connector in the inserted state via a transmission gap.
- the transmitting coil of the mating connector is acted upon by an alternating voltage, which induces a voltage in the receiving coil of the plug, which is used after rectification, to a provided in the connector evaluation for the To operate measuring signals.
- the measuring electronics are modulated onto a light source via the evaluation electronics so that the measuring signals can be transmitted galvanically separated to the mating connector in the form of light signals.
- the specified inductive energy transmission is suitable for the purpose of use only for the transmission of small power to supply the measuring electronics and the light source suitable for signal transmission.
- the high wear resistance makes contactless inductive energy transfer interesting also in the field of automation, for example for the transmission of energy to a robot tool.
- An inventive plug-in device for contactless inductive energy transmission from a primary part to a secondary part, each having at least one coil, which are inductively coupled to each other, is characterized in that the at least one coil cooperates with at least one ferrite core.
- the ferrite core increases the magnetic flux by its permeability so that even with small sizes of the plug-in device and small transmission surfaces higher electrical power can be transmitted. An energy transfer is already possible by the high magnetic flux, even if the primary and the secondary part are not (yet) in a position in which the distance between them is minimal, but if there is a gap between them.
- At least one inverter with electronic components is arranged integrally with the coil and the ferrite core in a housing in the primary part.

- the electronic components in Primärg. Secondary part each arranged on a circuit board, which is thermally coupled via a heat transfer medium with the ferrite core. Due to the thermal coupling of the respective ferrite core is heated by the converted power loss in the electronic components.
- their power losses due to magnetic reversal processes decrease with increasing temperature.
- the temperature increase at the ferrite core achieved by the thermal coupling leads to lower losses in the ferrite core, as a result of which the overall efficiency (transmission efficiency) of the plug-in device increases.
- the interior of the housing is sealed against a surrounding medium, in particular with respect to a surrounding liquid.
- the plug-in device can be used in dusty, sandy or humid environments. Also, for example, use underwater is possible.
- An operating method according to the invention for a plug-in device for contactless inductive energy transfer from a primary part to a secondary part is characterized in that the primary part carries out a measurement of operating variables of a primary coil used for inductive energy transmission and inhibits energy transmission depending on the measured operating variables. In this way it can be recognized by the primary part, if either no secondary part or a non-matching or a defective secondary part for inductive coupling faces the primary part. Especially with a plug-in device with the potential for transmission of higher electrical energy is prevented so that poses a threat from the primary part.
- the operating variables relate to a voltage at the primary coil and / or a current through the primary coil, which results when the primary coil is charged with an alternating voltage signal with predetermined parameters.
- the predetermined parameter quantities, in particular a duty cycle, of a PWM method, which is used to generate the alternating voltage signal preferably relate to this.

- Elements which are assigned to the secondary part 1 ' also referred to below as secondary-side elements, bear reference symbols with a corresponding apostrophe.
- primary-side and secondary-side elements which have the same or a comparable function, are provided with reference numerals with the same numbers. Unless explicit reference is made to the primary or secondary side in the following, reference symbols without apostrophes are used which refer to both sides.
- Primary part 1 and secondary part 1 'each have a housing 2, which may be made of a usual for plug housing material such as plastic, aluminum or stainless steel or the like.
- the housing 2 are designed half-shell-shaped, with its front side is closed with a front panel 3.
- a cable feedthrough 4 for a connection cable 5 is introduced into the housing 2.
- a coil 10 is in each case arranged, which is wound on a ferrite core 1 1, or is wound on a bobbin, which is inserted into the ferrite core 1 1.
- the coil 10 may be wound with a single conductor. To reduce the skin effect, however, a use of multicore Hochfrequenzlitze is preferred.
- the ferrite core 11 is a round pot core on the primary and secondary side with an outer edge 12 and an inner dome 13 concentric therewith.
- a core is also referred to as a (cylindrically symmetric) E core.
- the cross sections of the outer edge 12 and the inner dome 13 are preferably approximately the same size in order to achieve a homogeneous magnetic flux density, taking into account the different stray fields in the ferrite core 1 1.
- the use of ferrite cores with different geometry is also possible. For example, square or rectangular cores may have round or square or rectangular heights. cores are used. It is also possible to use coils without bobbins, eg with conductors glued together.
- the respective front panel 3 towards the ferrite cores 1 1 are open, whereas on the opposite side of the outer edge 12 and the inner dome 13 are connected to each other via a pot bottom.
- the coil 10 is inserted in each case in the here annular trench between the outer edge 12 and the inner dome 13.
- a possibly still existing gap between the outer and inner edge of the coil 10 and the ferrite core 1 1 may be filled with a heat-conducting medium.
- the primary part 1 and the secondary part 1 ' With their front panels 3, 3' facing each other brought to a close distance to each other for contactless inductive energy transfer.
- this distance which forms a transmission gap, is shown as the transmission distance d.
- the transmission distance d is in the range of 0 to a few millimeters or centimeters, depending on the size, in particular the diameter of the coils 10 or ferrite cores 11.
- the primary-side coil 10 hereinafter also referred to as the primary coil 10, subjected to an alternating current.
- a resonant circuit is formed from the primary coil 10 and a resonant capacitor whose frequency is in the range of a few kilohertz (kHz) to a few hundred kHz, with a frequency in the range of a few tens of kHz being particularly preferred.
- the alternating current which is applied to the primary coil 10, is provided by an inverter.
- a pulse width modulation method PWM
- the inverter is located together with monitoring and control devices on a circuit board 20 within the housing 2 of the primary part. 1 In the figure, 20 electronic components 21 are shown as an example on the board.
- the resonant circuit is slightly over-resonant, ie at frequencies above the resonant frequency operated.
- secondary coil 10' In an energy transfer due to the magnetic coupling between the primary coil 10 and secondary coil 10 ', hereinafter referred to as secondary coil 10', which is particularly efficient by the existing ferrite cores 1 1 and 1 1 '.
- a voltage is induced, which is available after rectification, voltage conversion - and possibly voltage stabilization - as an output voltage on the connecting cable 5' for delivering the transmitted energy.
- the electronic components on the secondary side are likewise arranged on a circuit board 20 ', wherein in this case individual electronic components 21' are again shown by way of example.
- the secondary coil have a center tap, so that a synchronous rectifier can be used.
- the ferrite cores 1 1, 1 1 allow a high magnetic flux density, through which an efficient energy transfer is possible even with a small coil volume.
- the transmission is relatively tolerant of a lateral displacement of the primary part 1 and the secondary part 1 'against each other possible. This is for example in the automation area of great advantage, since it can be dispensed with a high positioning accuracy for establishing a conventional contact-type connector.
- no interlocking guide or positioning elements are provided, which would align the primary part 1 and the secondary part 1 'when nesting laterally to each other. Due to the absence of such elements, the primary part 1 and the secondary part 1 'can also be brought into the operating position or separated from one another by a lateral movement, that is to say a movement in the direction of the extent of the front plates 3, 3'. This proves to be particularly advantageous in the field of automation, since an additional axial movement of primary and secondary part 1, 1 'to each other for establishing or disconnecting a connector is not required. Depending on the intended application, however, such guiding or positioning elements may also be provided in alternative embodiments.
- Both the primary part 1 and the secondary part 1 'are between the respective ferrite core 1 1 and the board 20 réelleleitmatten 14 are arranged.
- the electronic components 21 arranged on the printed circuit board 20 represent a large loss source in the transmission path. The generated by these components 21
- Heat loss is transmitted through the heat conducting mats 14 on the ferrite core 1 1.
- the ferrite core 1 1 heats up during operation to a higher operating temperature than would be the case without the thermal coupling to the board 20.
- the efficiency of energy transfer increases, as can be seen from FIG.
- a potting compound can be used to thermally couple the circuit board 20 and the ferrite core 1 1.
- FIG. 3 shows dependencies of the specific power loss P v for an exemplary ferrite material of the ferrite core 1 1 as a function of the operating frequency f in logarithmic plots. The dependence is given in several pairs of curves for different magnetizations varying between 50 milli-Tesla (mT) and 200 mT. For each pair of curves, the upper, solid curve indicates the specific power dissipation at 25 ° Celsius, ie approximately room temperature, and the lower dashed curve the specific power loss at a temperature of 100 ° Celsius of the ferrite core 1 1. It can be seen that over the entire frequency range shown for each magnetization used, the losses at a lower temperature in the ferrite core 11 are greater than at a higher temperature.
- mT milli-Tesla
- the primary part 1 is "operated empty", which would, however, mean an unnecessarily high idling energy consumption for the primary part and what is undesirable with regard to an unwanted emission of electromagnetic impurities If this is positioned opposite a conductive, eg a metallic surface, the currents induced in the metallic surface can heat them up, and the primary part should not be operated with a non-matching or defective secondary part.
- FIG. 4 describes an operating method for a plug-in connection for contactless inductive energy transmission, which prevents both increased idling energy consumption of the primary part 1 and uncontrolled energy transfer to another element than a suitable secondary part 1 '.
- the illustrated operating method can be carried out, for example, with the plug-in device described above in connection with FIGS. 1 and 2. It is therefore described by way of example with reference to this plug-in connection.
- a first step S1 an AC voltage signal with predetermined first parameters is output to the primary coil 10.
- predefined first parameters for a PWM method are set, for example a duty cycle.
- a delay time of, for example, 15 milliseconds may be provided here, which serves for the settling of the system to the settings in step S1.
- Step S2 is optional and may be omitted if the system requires only a negligibly short time to implement changed settings.
- a step S3 the current through the primary coil 1 as an operation amount of the primary coil 10 is measured. Only if the second Därteil 1 'with respect to the primary part 1 is present, the measured current remains below a predetermined, correlated with the first parameters current limit. Additionally or alternatively, it may be provided, in addition to the current through the primary coil 1 itself, to consider the rate of change of this current.
- a DC link capacitor is usually provided at the rectified voltage, the charging of which, after the setting of an AC voltage signal with the predetermined first parameters, leads to a current change of the current through the primary coil 1 with a characteristic time characteristic. It can thus be determined both via the absolute value of the current and via its rate of change in step S3, whether a secondary part 1 'faces the primary part 1.
- step S10 in which the primary coil 10 is no longer energized, in other words, no energy transfer takes place.
- step S1 1 for a relatively long delay time, which is 0.5 seconds by way of example here.
- step S1 in which again a first amplitude is applied to the primary coil 10.
- step S1 in which again a first amplitude is applied to the primary coil 10.
- step S3 Secondary existing capacitor is discharged via a discharge mechanism in the time of step 1 1, so that when restarting the process with the step S1 starts under the same initial conditions.
- a current sink can be present on the secondary side, which is switched off after the coupling of primary part 1 and secondary part 1 '(see step S9) in order to reduce the power consumption. If it is determined in step S3 that the measured current is below the limit value and / or shows the expected time dependence, the method is continued after a further short delay time in step S4 with step S5, in which the height of the voltage at the primary coil 10th is determined as a further farm size. If it is determined in step S5 that the voltage does not satisfy certain predefined requirements, the method in turn branches to step S10. On the other hand, if the voltage is in the predetermined range, the process proceeds to a step S6.
- step S6 the primary coil 10 is supplied with an alternating voltage signal having predetermined second parameters.
- second parameters of the PWM method are set analogously to step S1, again using the duty cycle, for example.
- step S7 the voltage applied to the coil is again measured in a subsequent step S8. If this voltage does not satisfy second predetermined voltage criteria which are correlated with the second parameters, the system branches again to step S10. Only if it is determined in step S8 that the second criteria are met, the method is continued with step S9, in which the primary coil 10 is operated for energy transmission. During the operation of the primary part 1 in step S9 is continuously the
- step S10 Current determined by the primary coil 1 and / or by switching elements of the inverter. If the absolute value of the current exceeds a certain limit, the operation is stopped and the process branches to step S10. For example, an excessively high load on the secondary side is detected on the primary side. Furthermore, based on the currents, the waveform at the output of
- step S10 Inverter checked. Too large deviations of the waveform from a sinusoid indicate an incorrect secondary side. Also, removal of an otherwise matching secondary part 1 'can be detected. In such a case, the process also branches to step S10.
- the illustrated method has the advantage that an incorrect secondary side is detected on the primary side. There is no feedback from the secondary part 1 'to the primary part 1 necessary to ensure safe operation of the primary part 1.
- the system may be exposed to temperatures in a wide temperature range, for example between -20 ° C and 100 ° C, due to the ambient conditions and / or due to its own power loss.
- the parameters and / or limit values used in the method, for example in steps S3 and S8, can be predetermined as a function of temperature in order to ensure a correct process sequence with reliable detection of a correctly operating secondary side at every possible operating temperature.
- a safety mechanism based on feedback of a secondary part to a primary part can alternatively or additionally be used.
- the connector can be provided to constantly determine the size of the air gap in operation and check.
- the air gap can be determined based on a detuning of the resonant circuit via the resonant frequency, possibly in conjunction with the current flowing in the primary coil. It can be provided to prevent the transmission of energy when a predetermined distance d (see FIG.)
- it is possible to provide energy buffering on the secondary side for example by means of a capacitor with a high capacity, in order to maintain operation or emergency operation in the secondary side in the event of a temporary power failure, for example during a tool change.
- this is designed for operation in a liquid medium.
- the housing 2 is sealed in connection with the front panel 3 with respect to this liquid medium.
- a heat insulation, z. B. in the form of a thin air gap between the ferrite core 1 1 and the front panel 3 vorge- to achieve the previously described effect of improving the efficiency by heating the ferrite core 1 1 also within a rather cooling liquid surrounding medium.
- the transmission via the transmission gap d can be optimized for changed magnetic susceptibilities of the liquid medium.
- the seal between the housing 2 and the front panel 3 advantageously also provides protection against dust and dirt.
