Description of the Related Art In an air conditioner using an electric compressor, an electric compressor driving device for driving an electric compressor for air conditioning supplies a large current to the electric compressor, so that electric noise is large and interferes with a vehicle-mounted radio. Also, the large fluctuation of the current affects the durability of a DC power supply such as a battery for supplying a current. Therefore, as shown in the voltage / current waveform diagram of FIG. 3, it is necessary to smooth the current supplied to the electric compressor to suppress electric noise and current fluctuation. Therefore, as shown in the circuit diagram of the conventional air conditioner for an electric vehicle in FIG. 5, a capacitor having a large capacitance is provided at a place where the electric compressor driving device 1 is supplied with electric power from a DC power source via a switching device 3, such as a battery 2. 11 must be provided.

させるなどの問題が生じる。However, when such a capacitor having a large capacitance is provided, a large charging current flows to the capacitor at the moment when the switchgear 3 is closed because the internal resistance of both the DC power source such as a battery and the capacitor is small. As a result, surge voltage is generated due to resonance with an inductance component such as wiring from a battery as shown in the voltage / current waveform diagram of FIG. Problems arise.

The opening and closing device 3 is closed, power is supplied from the battery via the opening and closing device, and the electric compressor for air conditioning is driven by the electric compressor driving device.

れる。When the switchgear 3 is closed, the voltage difference E-Vt between the predetermined voltage Vt detected by the input voltage detecting means 7 and the voltage E of the battery 2 is determined by the internal resistance of the battery 2 and the capacitor 11. A current divided by the sum flows through the battery 2, the fuse 10, the switchgear 3, and the capacitor 11.
【００１０】よって、この電流がヒューズ１０、開閉装

Since the voltage E is higher than the charging start time, the voltage difference E−Vt becomes large, and the current may exceed the capacity of the fuse 10 and the switching device 3. As a result, problems such as a blow of the fuse 10 and breakage of the switchgear 3 occur. When the sum of the internal resistances of the battery 2 and the capacitor 11 is 1 ohm and the voltage E is 320 V, the voltage Vt is 290 V, so that the voltage becomes 30 A, which exceeds the capacity 10 A of the fuse 10 and the switching device 3.
