摘要:
A washer dryer including a DC power supply generator that generates a DC power supply from an AC power supply; a heat pump that circulates refrigerant between a compressor, a condenser and an evaporator; an air circulatory path that circulates air between the condenser and the evaporator; a first inverter circuit that receives the DC power supply to drive a compressor motor; a rotary tub disposed rotatably within an exterior tub; a rotary tub motor that directly drives the rotary tub at least during dehydration; a second inverter circuit that receives the DC power supply having an output terminal connected to windings of the rotary tub motor; a voltage detector that detects DC voltage occurring between the second inverter circuit and a power supply bus; a brake controller that controls the DC voltage within a predetermined range by controlling a regenerative electric power when braking is applied.
