Abstract

A PFC inductance and battery boost transformer integrate topology structure comprises a voltage stabilizing module and a power supply boost module; The voltage stabilizer module works in the mains mode. The voltage stabilizer module provides stable positive and negative BUS voltage and corrects a power factor. When the mains power is abnormal, the power supply boost module switches to the battery-powered operation state, and converts the battery voltage boost to a stable positive and negative BUS. The purpose of the invention is to provide an PFC inductance and battery boost transformer integrate topology structure, which reduces the cost, reduces the volume and simplifies the circuit.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an integrated topology structure of a PFC inductor and a battery step-up transformer. Background technique [0002] Low battery voltage online UPS usually refers to a type of equipment with an output capacity below 5kVA. Because of its small power capacity, the battery pack voltage of this type of equipment is usually relatively low, generally not exceeding 96V. Most of the popular UPSs on the market Concentrate between 24-48V. As we all know, the online UPS realizes its functions through two-stage conversion: 1. The running state of the mains power is converted by the PFC circuit to realize the AC-DC process, and provides a stable BUS DC voltage for the inverter unit. 2. In the battery running state, a booster unit boosts the lower battery voltage to 380V to provide a stable BUS DC voltage for the inverter unit. For equipment with a capacity greater than 5kVA, beca...
