Abstract

PURPOSE:To attain a switching circuit that is compact, light weight, high reliability, low noise and capable of controlling an output current waveform optionally. CONSTITUTION:Between the DC power supply 1 and a control circuit 9, a bridge by transistors Tr 2-5 and light receiving Tr 6, 7 are connected. And, it has been arranged that under control of the circuit 9, any one of light emission diodes 6', 7' which froms a pair of a photocoupler with Tr 6 and 7 respectively will operate. Noew, when diodes 6', 7' are drived alternately by a square wave, the current waveform of a load 8 becomes like A. And when it is drived by a delta or sine wave, a current waveform like B or C is attained respectively. As mentioned above, because there has been no oscillator, transformer, mechanical switch and the like, it is available to obtain the expected effect.
