Abstract
In an air conditioner including a control unit receiving a power from a switching power supply, the switching power supply is connected to a DC power source without passing through a switch device or power application device. The output of the switching power supply is connected to a capacitor via a diode. The control unit is able to operate even when the capacitor to be charged via the power application device is not charged. Accordingly, the motor-driven compressor may start to operate quickly.
