A power supply system for driving a compressor 17 of an air conditioner has a smoothing circuit 16 connected between a three-phase bridge rectifier 20 and an inverter 30. The smoothing circuit 16, which may comprise a capacitor as shown, is capable of removing ripple to ensure normal operation of the inverter 30 even when a single-phase voltage is applied. Thus, the air conditioner is operable on either a single-phase or three-phase voltage and the standardization of various parts and equipment is facilitated. <IMAGE> |
