Embodiment Construction
[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.
[0022] An integrated topology structure of a PFC inductor and a battery boost transformer, including a voltage stabilizing module and a power supply boost module;
[0023] The voltage stabilizing module works in the commercial power mode, and the voltage stabilizing module provides stable positive and negative BUS voltages and corrects power factor;
[0024] The power supply boost module turns to the battery-powered working state when the mains power is abnormal, and boosts the battery voltage into a stable positive and negative BUS.
[0025] Such as figure 1 and figure 2 As shown, the topological structure of the present invention is the front-end circuit unit of the online UPS, which aims to provide stable positive and negative BUS power for the following inverter unit (the circuit that converts direct cu...
