| 摘 要： | 对一种新颖前沿的单相双向开关型AC/DC维也纳(Vienna)PFC拓扑进行研究,采用数字化前馈补偿,改善传统双环输入电流畸变问题,通过引入MCM数字前馈占空比补偿,使得系统在负载全功率范围内,输入电流波形不受电感连断续下模型差异的影响,得到了较好的PFC效果。通过理论分析,推导出MCM前馈占空比补偿的表达式,最后搭建1 k W的Vienna-PFC样机,并验证了方案的可行性。

| Abstract: | This paper presents a novel front-end topology of a single-phase bidirectional switch AC/DC Vienna-PFC. A digital feed-forward compensation method is adopted to solve the problem of traditional double-loop input current distortion. MCM digital feed-forward duty cycle compensation is introduced so that the input current waveform is not affected by model variance over the full power range, and a good PFC effect can be achieved. An expression of the MCM feed-forward duty cycle compensation is deduced through theoretical analysis. Finally, a 1KW prototype Vienna-PFC is constructed, and the feasibility of the scheme is verified on the platform. |
