Three new composite soft switching configurations for power inverters are p
resented. Each configuration incorporates an inductor to limit switch di/dt
and diode reverse recovery current at turn-on, and realizes zero current s
witching at turn-off, with minimum active devices or passive components. Di
fferent features and applications of the configurations are considered. Sim
ulations of three different inverter configurations are performed using PSp
ice and circuit switching waveforms are given, and experimental results con
firmed analysis and simulations.
