Abstract:
A motor drive apparatus includes a converter configured to convert AC power inputted by an AC power supply to DC power and to output the same to a DC link, a DC link capacitor provided for the DC link, an inverter configured to convert the DC power in the DC link to AC power for driving a motor and to output the AC power, a DC voltage detection unit configured to detect a value of DC voltage applied across the DC link capacitor, an AC voltage detection unit configured to detect a peak value of AC voltage on an AC input side of the converter, and a leakage current detection unit configured to detect a leakage current caused by driving the motor, based on the value of DC voltage detected by the DC voltage detection unit and the peak value of AC voltage detected by the AC voltage detection unit.
