• the invention relates to a device for controlling an actuator. Furthermore, the invention relates to a system comprising such a device, an actuator and a transmitter and a method for controlling an actuator.
• the transponder is an electronic circuit arrangement that exchanges data with a communication partner in a contactless manner.
• the transponder can be designed so that it uses the supply voltage required for its operation by means of a coil, which is also used for data transmission from the field generated for data transmission.
• the transponder can have a shunt regulator, with which the quality of the resonant circuit and thus the supply voltage of the transponder can be set by connecting a controllable resistor in parallel with the coil of the transponder.
• the device according to the invention for controlling an actuator has an energy store for supplying the actuator, a receiving unit for contactless reception of a control signal and a control unit for controlling the energy supply to the actuator depending on the control signal.
• the special feature of the device according to the invention is that energy for charging the energy store can be supplied via the receiving unit.
• the invention has the advantage that only an energy store with a relatively small capacity is required, which is sufficient for a single activation of the actuator.
• Another advantage is the high operational reliability of the device according to the invention, which results from the fact that the energy store can be charged via the receiving unit, so that a sufficient amount of energy can always be provided for the activation of the actuator in a simple manner and the risk of inoperability because of insufficiently charged energy storage does not exist.
• the battery change required in known devices is eliminated.
• it is also advantageous that actuators with high power consumption can also be operated for a short time.
• the two current paths are each influenced in such a way that a second partial current flowing through the second current path assumes a maximum possible value under the respective operating conditions.
• This has the advantage that an optimal charging of the energy storage is possible without deviating from the default value for the regulated voltage.
• a further advantage is that the excess energy to be dissipated for the regulation of the voltage to the preset value is at least partially or completely supplied to the energy store and is therefore not released in the form of heat.
• the first current path and / or the second current path can each be influenced by means of a controllable resistor, in particular a transistor.
• the energy store serves exclusively to supply the actuator and not to supply the control unit.
• the actuator can be controlled via a connecting device for establishing a temporary connection between the energy store and the actuator.
• a control signal is transmitted to the control device without contact and the actuator is connected to an energy store of the control device depending on the control signal.

• the first exemplary embodiment of the device according to the invention is of a very simple design and has no possibility of regulating the second partial flow 12 with which the capacitor 7 is charged.
• the supply voltage at the beginning of the charging process assumes very small values due to the very large second partial current 12 and is therefore initially insufficient to operate the transponder circuit 8.
• the transponder circuit 8 is thus not ready for operation with the capacitor 7 largely discharged from the point in time at which the antenna coil 2 is exposed to an alternating magnetic field.
• a sufficient supply voltage for the operation of the transponder circuit 8 is only available when a certain charge state of the capacitor 7 has been reached and the second partial current 12 has decreased accordingly.
