Abstract
The invention concerns a circuit arrangement for the wireless transmission of a control signal to the control path of a controlled semiconductor valve, particularly a thyristor. The control signal is provided here to modulate a high-frequency transmitter which is arranged at some distance from a high-frequency receiver which contains a demodulator, whose output signal is applied to the control path of the semiconductor valve. For return transmission of information regarding the state of the semiconductor valve, the receiving antenna of the high-frequency receiver is provided as a transmitting antenna and the transmitting antenna of the high-frequency transmitter as a receiving antenna.
