In a UPS system, a DC-AC converter is always used to convert the DC power from the batteries to AC power used to supply the load. The basic scheme also includes a battery pack, a battery charger which converts AC power from the grid into DC power, and a transfer switch to supply the load from the mains or from the energy storage elements if a line voltage drop or failure occurs.图1.离线UPS系统方框图
