Abstract :
In this paper, a novel zero current soft switching (ZCS) PWM single-ended push pull (SEPP) multi-resonant inverter is proposed. Its topology structure and power control scheme is introduced. The theoretical operating waveform of this inverter which works in steady state is proposed. Its operating principle is described by analyzing the equivalent circuit of the switching mode of the ZCS asymmetrical PWM inverter. In order to expand the zero current soft switching operating range, PDM control scheme is proposed. The rationality of theoretical analysis is verified by the simulation results and results analysis.
