A rectifier (22) rectifies the three-phase voltage from power supply (21), to direct current (DC) voltage. A voltage reduction unit (23) reduces and stabilizes the rectified DC voltage. An inverter unit (24) inverts the stabilized DC voltage, as three-phase alternating current (AC) voltage for driving three-phase induction motor (25). An independent claim is also included for driving method of three-phase induction motor which drives air conditioner. |
