Abstract

See full text

In a power converter for converting DC power from a DC power source into AC power and supplying the AC power to a single-phase winding or multi-phase windings, a controller controls first and second inverter circuits and performs first power conversion control to lock open/closed states of switching elements in the second inverter circuit and switch open/closed states of switching elements in the first inverter circuit, and second power conversion control to lock open/closed states of the switching elements in the first inverter circuit and switch open/closed states of the switching elements in the second inverter circuit. The controller is configured to perform either the first power conversion control or the second power conversion control when an effective value of drive current through each winding is less than a threshold, and otherwise switch between the first power conversion control and the second power conversion control.
