Abstract
Switching stress on the switches of a DC-to-AC inverter bridge are reduced, and fall time losses are reduced, by driving the inverter from a source of constant current, by operating the bridge in a mode in which all the switches are periodically rendered conductive simultaneously, and by tuning the load to produce resonant currents which reduce the currents through the switches of the inverter at the moment of turn-off.
