| description | A motor driving apparatus includes: an inverter that includes a plurality of switching elements and that is configured to output AC power to a motor by a switching operation of the plurality of switching elements, a switching unit that includes a relay and that is configured to switch a connection mode of the motor by an operation of the relay, and an inverter controller configured to control the inverter and the switching unit. The inverter controller is configured to, based on the relay being turned off, apply a reverse voltage to the relay. |
