A DC/DC circuit of an uninterrupted power supply (UPS). The DC/DC circuit is a bidirectional DC/DC circuit, and the bidirectional DC/DC circuit is connected between a bus bar and a battery. In a charging mode, the bidirectional DC/DC circuit obtains power from the bus bar and charges the battery; and in a discharging mode, the bidirectional DC/DC circuit obtains power from the battery, and supplies power to the bus bar. In the UPS, the charging circuit and the discharging circuit are integrated into a DC/DC circuit, the DC/DC circuit being a bidirectional DC/DC circuit, and both a charging function and a discharging function are achieved. This allows for a reduction in UPS size, a reduction in cost, and the centralization of key elements, thereby promoting product miniaturization. |
