POWER CONVERTER

The purpose of the present invention is to obtain a power converter that can further improve the maintainability after the power converter is stopped without reducing the power conversion efficiency when the power converter is operating. The power converter includes an inverter 5 that converts input DC power into AC power and outputs the AC power, a capacitor 6 connected between input side terminals of the inverter 5, a discharging unit 7 that is provided to be connectable in parallel with the capacitor 6 and discharges electric charge stored in the capacitor 6, and an opening/closing unit 8 that is connected in series with the discharging unit 7 and opens and closes electrical connection between the capacitor 6 and the discharging unit 7.
