Abstract
A power inverter for a polyphase load such as an AC motor is provided which is designed to minimize an on-off switching loss of transistors installed in the inverter. The inverter works to disenable switching operations of the transistors for each phase in a first cycle during which a corresponding output current is high in level and partially disenable the switching operations in a second cycle following the first cycle during which the corresponding output current is middle in level.
