摘要
An apparatus for balancing a voltage of a direct current (DC) link capacitor of an inverter is provided. The apparatus of the present disclosure includes a switching unit connected to a node (a reference point) between the first and second resistors, which are connected in series to each other, and a node (a neutral point) between the first and second capacitors, which are connected in series to each other, and configured to short and open between the reference point and the neutral point, and a control unit configured to control the switching unit to short between the reference point and the neutral point when a voltage of the reference point (a reference point voltage) and a voltage of the neutral point (a neutral point voltage) are different from each other.
