Abstract
An inverter unit includes a first temperature detector that detects a first temperature of at least one of semiconductor elements and a periphery of the semiconductor elements, current detectors that detect a current of a motor, and a controller that switches a modulation mode of the motor to a two-phase modulation mode or a three-phase modulation mode on the basis of a detection result of the first temperature by the first temperature detector and detection results of the current by the current detectors.
