| PROBLEM TO BE SOLVED: To abate inverter loss in a motor-driven compressor and reduce the risk of electric leakage.SOLUTION: An inverter 27 includes a motor drive circuit 28 and a main control computer C1 for controlling the motor drive circuit 28. When a startup command is inputted, the main control computer C1 performs three-phase modulation control and calculates a discharge amount Qx of liquid refrigerant discharged from inside a motor housing 18 since the time point of start of the three-phase modulation control. When the calculated discharge amount Qx of a liquid refrigerant is less than a preset reference amount Qo, the main control computer C1 continues the three-phase modulation control. When the calculated discharge amount Qx of liquid refrigerant is equal to or larger than the preset reference amount Qo, the main control computer C1 switches from the three-phase modulation control to two-phase modulation control. | ||||||
