Abstract

A UVW-phase inverter control circuit has a control function of generating a UVW-phase inverter control signal. An XYZ-phase inverter control circuit has a control function of generating an XYZ-phase inverter control signal. The control function of the UVW-phase inverter control circuit is stopped during execution of a BIST. A phase conversion unit generates a UVW-phase inverter control signal by phase conversion for the control signal from the XYZ-phase inverter control circuit. During execution of the BIST by the UVW-phase inverter control circuit, a selector outputs the inverter control signal from the phase conversion unit as a UVW-phase inverter control signal, and a selector outputs the inverter control signal from the XYZ-phase inverter control circuit as an XYZ-phase inverter control signal.
