Abstract:
1. A power converter comprising: a switching circuit comprised of a plurality of switching elements connected in series; a smoothing capacitor connected in parallel to the switching circuit; a power-converting driver that drives the plurality of switching elements for power conversion; a power-converting power supply circuit that outputs, to the power-converting driver, a voltage that drives the plurality of switching elements to perform the power conversion; a discharging driver that drives the plurality of switching elements for discharging charge stored in the smoothing capacitor; and a discharging power supply circuit that supplies, to the discharging driver, a voltage for driving the plurality of switching elements, wherein the discharging driver drives, based on the voltage outputted from the power-converting power supply circuit, the plurality of switching elements to discharge the charge stored in the smoothing capacitor.
