| description | The present invention relates to a charging and discharging control apparatus of a DC link capacitor and a control method thereof. The charging and discharging control apparatus (200) of a DC link capacitor includes a charging power supply unit (210) for storing DC power and supplying an input voltage, an inverter unit (250) for converting the DC power into AC power, a DC link capacitor unit (240) for repeating charging and discharging so that the input voltage inputted to the inverter unit is limited within a limit voltage, a switch unit (220) for controlling the input voltage applied to the DC link capacitor unit by performing an on (close) or off (open) operation, and a switch control unit (230) for distributing the input voltage and generating and outputting a control signal for controlling the on-off operation in the switch unit. Accordingly, the present invention can limit an overcurrent flowing in the DC link capacitor and an inverter at a fast reaction speed.
