Definitions
- the invention relates to an on-board electrical system power supply for an electronic control circuit, for example for dimmer arrangements for lights, the output voltage of one or more circuit units connected in parallel is influenced, in detail according to the generic term of claim 1.
- the outputs of the circuit units can be understood as retroactive control outputs.
- At a retroactive control output is connected to a control voltage by a load resistance in one Stress circle can be reduced and with decreasing Voltage causes an adjustment process.
- a retroactive control output is connected to a control voltage by a load resistance in one Stress circle can be reduced and with decreasing Voltage causes an adjustment process.
- electronic ballasts for fluorescent lamps which have a voltage at the control outputs that are below Load in one at the control outputs more or less short-circuiting load circuit at the control outputs have a correspondingly falling voltage, which on a fluorescent lamp connected to the electronic ballast dimmed accordingly.
- the one or more control outputs connected in parallel The voltage provided should be different Use cases between specified values are regulated.
- the control outputs can be used as voltage sources with a Internal resistance can be viewed through a common variable resistance can be charged to to effect an actuating process on an input side.
- variable resistance adjust the voltage drop so that the desired voltage is present at the control output, the one the corresponding desired input value is assigned.
- Control outputs With several parallel ones Control outputs, the alternative internal resistance changes for all control outputs arranged in parallel in Depends on their number. In practice, therefore Regulation required.
- Such a scheme by electronic circuitry is required in practice a dedicated on-board power supply, e.g. through a Power supply unit, however, requires additional circuitry has an unfavorable economic impact.
- the invention has for its object an on-board power supply to develop the kind described no own on-board power supply required.
- the on-board power supply for the electronic control circuit becomes from the actual value of the output voltage based.
- the regulation is done by a variable Resistor, the control outputs, or the outputs of the circuit units, jointly loaded and its voltage drop the voltage drop at the imaginary internal resistance there so that the voltage at the control output is pending, the input side an assigned desired Condition corresponds.
- the electronic control circuit from the respective Actual value of the voltage would in principle mean that the respective Actual amount of voltage for the on-board power supply is not could be exceeded. Exceeding the actual value However, it is possible that the electronic control circuit a reference element for forming a reference voltage contains which reference voltage as supply voltage for a demodulator is used. The reference link to education a reference voltage ensures that the lowest expected voltage is sufficient, the control circuit a measure to give for a unit in connection with the control signal a corresponding multiple as the target value for the Can derive control part.
- the electronic control circuit can be from a receiving stage for coded control signals. Especially the control signals can be provided in pulse width modulation will. In particular, the vehicle electrical system voltage supply executed in detail according to claim 2 or claim 5 be.
- control circuit In practice, it is often required that the control circuit should be galvanically isolated from the actuator.
- the vehicle electrical system power supply can easily solve this requirement so that the receiving stage with an optocoupler works, in particular according to claim 6.
- the power supply according to FIG 1 wins from a number from retroactive control outputs 1 to 4, generally to n, the on-board power supply for an electronic control circuit 5.
- the voltage available for the electrical system supply UR corresponds to the regulated voltage UR. she is designated 8 below.
- the common load through the load resistance 6 of the The voltage of the control outputs depends on Control signals 7.
- the load resistance 6 becomes corresponding changed so that a regulated voltage 8 is achieved becomes. This also serves to obtain the vehicle electrical system voltage for the electronic control circuit 5.
- FIG 2. An embodiment for the electronic control circuit 5 is shown in FIG 2. It works with a reference link 9 to form a reference voltage. This will from the voltage of the control outputs 1-4 to that for the regulation permissible lowest actual value obtained. This is ensures that the lowest actual value is a unit reproduces a corresponding multiple through the Control value can be formed.
- the setpoint as a product the control value of the control signal 7, for example one pulse width modulated signal, and the reference voltage as Unit is fed to a control part 10.
- a coded one Control signal is demodulated in a demodulator 11 and taking into account the reference voltage the control part 10 supplied as a setpoint via a setpoint line 12. Of the The actual value of the voltage 8 is via an actual value line 13 Control part 10 forwarded.
- the control part acts on a valve 14, for example a controlled semiconductor valve, which is connected between conductors, between which the to regulating voltage 8 is present.
- the input stage 15 works for the control signal 7 with an optocoupler, which creates a voltage separation between an actuator for the supply of the control signal 7 and the control circuit is achieved as it is by the dividing line 16th is illustrated.
- the described power supply comes without an external one additional power supply as power supply for the electronic Control circuit off. This will make additional Terminals, wiring and components saved.
- the reference member 9 can expediently provide a reference voltage of 1 V. 10 V can be used for dimmable electronic ballasts the highest brightness and 1 V the adjustable lowest brightness mean.
- the use of individual power sources as they are on the market the disadvantage that the setting is temperature-dependent and would be relatively imprecise and that only a comparatively small one Number of control outputs could be switched.
- the invention worked with a control signal 7 in pulse width modulation and a voltage separation by an optocoupler can be reached in reception level 15.
- Essential is that the demodulator 11 only by the reference voltage of the reference member 9 is supplied, the one Voltage in the order of the lowest allowable Provides actual value voltage. This becomes the one to be regulated Tension 8 won.
- the demodulated setpoint is the Control part 10 supplied, which corresponds to the load of the retroactive control outputs changes.
- the burden can for example by a valve 14 in the form of a semiconductor valve, such as a transistor.
- the entire voltage supply to the control circuit 5 takes place So by the voltage to be regulated 8 itself, without one additional external power supply would be required.
