Abstract

PURPOSE:To obtain a power supply power at one electric device and to achieve signals in binary modulation according to amount of load, by producing a high frequency AC power at another electric device, making binary modulation according to transmitted signal and transmitting the result to one device via a load detector and an insulator. CONSTITUTION:An output of a high frequency oscillator 1 is in binary modulation according to a digital input data SD at a modulation circuit MOD of a modulation and demodulation section 2, the result is given to a switching circuit 3, and an AC voltage is produced across the primary coil of a transformer 4 according to a signal given to the circuit. A voltage across a resistor connected to a center tap of the transformer 4 is applied to a demodulation circuit DEM of modulation/demodulation section 2. At a demodulation circuit DEM of a modulation and demodulation section 5 at the secondary side of the transformer 4, the data signal SD and a clock CLK are demodulated from the induced voltage and applied to a signal processing circuit 7, the induced voltage is rectified at a rectifying circuit 6 and applied to the circuit 7 as a power supply power. A signal in binary modulation is outputted from the circuit DEM according to the amount of load.
