HALF BRIDGE RESONANT INVERTER

Abstract

The aim of this work is to develop a resonant inverter using half bridge inverter configuration which feed power to induction heater during positive and negative cycle of load current. Such system will substitute the using of full bridge configuration, hence a reduction in both cost and complexity. A full analysis of the proposed circuit using IGBTs at a frequency of 50 kHz, and a power of 1.8 kW is presented. The practical results agree with that of the simulation, and their waveforms are closely similar, so the proposed inverter is completely valid.
