摘要
介绍了一种有源功率因数校正电路。在传统不可控整流电路的基础上增加外围辅助电路,并以UC3854为核心部件控制功率元件的通断,使输入电流波形跟随输入电压波形。通过仿真波形分析及公式计算可知,功率因数校正技术能够使输入电流波形始终保持为正弦波,其相位能够与输入电压波形保持同步,输出端直流电压波形也较为平滑,是提高电路功率因数的一种有效手段。
This paper introduces a kind of active power factor correction circuit,the auxiliary circuit is added to the traditional non-controlled rectifier circuit.UC3854 is the core components.The input current waveform is forced to follow the input voltage waveform by controlling the switch state of the power components.By analyzing the simulation of active power factor correction circuit and non-controlled rectifier circuit with filtering capacitor,it can draw a conclusion that power factor correction technology can effectively improve the circuit power factor and keep the input current waveform as sine.Its phase is in accordance with the input voltage waveform and the output DC voltage waveform is relatively smooth.
