Zusammenfassung:An energy-efficient power inverter is disclosed which changes direct current provided at a pair of source terminals to alternating current at load terminals. The power inverter comprises a switch device and snubber circuit including a resisitance, a capacitance and a saturable core device for selectively removing the resistance from the snubber circuit. At saturation the core device effectively shorts the resistance out of the circuit, and upon coming out of saturation the device effectively reinserts the resistance for improved reduction in power losses during the switch operation.
