Abstract
A motor driving apparatus of the present invention includes a converter unit configured to convert an AC voltage into a DC voltage, a DC link unit configured to smooth the DC voltage by a capacitor to generate a DC link voltage, an inverter unit configured to convert the DC link voltage into a multiphase AC voltage for motor driving, short bars configured to electrically interconnect terminals of the DC link unit and terminals of the inverter unit, and a DC link voltage detection unit configured to detect the DC link voltage. At least parts of the short bars are located between the terminals of the DC link unit and terminals of the DC link voltage detection unit.
