This paper proposes a novel, power electronics system, a PC based load resonant cyclo-inverter, capable of converting a single phase AC supply of frequency fi into a single phase AC supply of frequency fo that is higher than the input frequency. Use of PC to control the trigger pulses has made it more versatile. It finds its application in induction heating, ballast and so many applications where high frequency reduces the size of equipment. The actual performance of this converter is obtained by simulating it on a software package PSPICE. Peripheral input-output and PC interfacing hardware has been developed using programmable devices. The trigger circuit has been tested qualitatively by observing various waveforms on CRO. The operation of proposed system has been found satisfactory.
