Abstract

PURPOSE:To obtain a power supply power through the rectification of an AC power and to achieve a plurality of signals, by binary modulation according to a signal producing and transmission high frequency AC power at one of electric devices and transmitting the power to another electric device at an insulator. CONSTITUTION:An output of a high frequency oscillator 1 is in binary modulation according to input data D1 at a modulation circuit 2 and applied to a switching circuit 3. A DC supply is interrupted according to the signal given at this circuit 3 and applied to the primary coil of a transformer 4. A data signal D and a clock signal CLK are demodulated at a demodulation circuit 5 connected to the secondary side of the transformer 4, and the signals D and CLK are applied to a signal processing circuit 7. The induced voltage of the transformer 4 is rectified into a DC voltage at a rectifying circuit 6 and applied to the processing circuit as a power supply power and the processing circuit 7 processes the signal D according to the prescribed function.
