Abstract
A device for stabilizing a direct current (DC) distribution system includes a capacitor unit charged by a DC voltage supplied by a power supply stage of the distribution system. The device further includes an inverter that has three pair of switching elements. The device also includes a voltage stabilization circuit constructed using one pair out of the three pairs of switching elements in the inverter. The device also includes a controller that controls the voltage stabilization circuit to alleviate instability of a DC voltage generated in a transient period.
