1. An air conditioner comprising:
- a power application device coupled seriously to a DC power source;
a switch device coupled in parallel with said power application device;
a capacitor charged by said DC power source via said power application device;
a voltage detector for detecting the voltage of said capacitor;
an output unit for driving a motor-driven compressor for air conditioning, receiving a power from said DC power source via said switch device;
a control unit for controlling said output unit; and
a power supply for supplying a power to said control unit, receiving a power from said DC power source without though said switch device and without through said power application device.

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.
