Three new composite soft switching configurations for power inverters are presented. Each configuration incorporates an inductor to limit switch di/dt and diode reverse recovery current at turn-on, and realizes zero current switching at turn-off, with minimum active devices or passive components. Different features and applications of the configurations are considered. Simulations of three different inverter configurations are performed using PSpice and circuit switching waveforms are given, and experimental results confirmed analysis and simulations.
