为设计高效率、低损耗的PFC电路,本文基于UCC28019进行电路设计。以UCC28019输出的PWM波形来控制Boost升压斩波为核心电路,使电路中的电容交替地充放电、电感交替的储存和释放能量,最后实现在输入AC20V~24V电压情况下稳定输出DC38V。测试结果表明,系统实现效率为95%左右,电压调整率小于1%,电源功率因数0.99。交流输入电压为19.0-25.8 V时,输出直流电压稳定性较好,电感无明显啸叫且纹波小,具有一定的带负载能力和实用性。In order to design the PFC circuit with high efficiency and low loss,this paper designs the circuit based on UCC28019.The PWM waveform output by UCC28019 is used to control boost chopper as the core circuit,which alternately charges and discharges capacitors,stores and releases energy by inductors,and finally achieves stable output of DC38 V under the input voltage of AC20 V~24 V.The test results show that the system achieves about 95% efficiency,the voltage adjustment rate is less than 1%,the power factor is 0.99,and the AC input voltage is 19.0-25.8 V.The output DC voltage stability is good,the inductance has no obvious whistle and the ripple is small,so it has certain load capacity and practicability.
