Abstract
A converter supplies an output voltage, generated by stepping down or up an input voltage from a DC power supply, to an inverter for driving an AC motor. In the converter in a boost mode, a buck circuit is stopped, a boost circuit is operated, and a first bypass switch is turned on to form a path from the DC power supply to the boost circuit. In a buck mode, the boost circuit (30) is stopped, the buck circuit is operated, and a second bypass switch is turned on to form a path from the buck circuit to the inverter.
