UPS参考设计建造采用离线拓扑AVR升压和电源的降压调节。该逆变器模块中包含的推挽型DC-DC转换器和DC-AC输出的全桥产生准正弦波的波形。This UPS reference design was built employing off-line topology with AVR boost and buck regulation of the mains. The inverter module contains the push-pull DC-DC converter and the DC-AC output full bridge generating a quasi-sine waveform.A microcontroller controls all UPS functions. It monitors the mains parameters (input/output mains voltage and phase, output inverter voltage, battery voltage, output current and output power) in order to ensure the proper level of the output voltage.
