单相有源功率因数校正电路的抗干扰设计
资料介绍
通过建立理想开关模型,以及对Boost拓扑结构进行分析,设计了一种加强输入抗干扰能力的开关控制策略,并应用于功率因数校正电路优化。仿真结果表明,该功率因数校正器结构简单、抗干扰能力强,在无干扰情况下,功率因数由0.667 8提高到0.922 2;在输入有干扰情况下,功率因数由0.557 4提高到0.805 0,且电压输出稳定,开关损耗低。
Boost topology was analyzed and a switch control strategy to strengthen anti-interference ability was designed which was applied to optimize power factor correction（PFC） circuits by establishing an ideal switch model.The simulation results show that this PFC has brief structure,wonderful anti-interference ability,and the power factor can be raised from 0.667 8 to 0.922 2 under no interference condition;while under interference it can be improved from 0.557 4 to 0.805 0 with steady output voltage and low switching loss.
