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 controller that controls a plurality of switches thereof to selectively enable an inverter circuit or a voltage stabilizing circuit of the DC distribution system. The device alleviates instability of DC voltage which may be generated in a transient period, or to drive a motor connected to the device.
