摘要

本文提出了一种具有多个开关单元的升压型功率因数校正(PFC)拓扑的新推广方法。它是基于两个或多个串联PFC拓扑通过一个或多个耦合电感并联连接。以最小有功功率器件数为优化准则，采用堆叠飞行电容器(SFC)多电平原理，将串联PFC拓扑推广到5个以上电压电平。通过7l串联PFC和9l串并联PFC三相拓扑的数值模拟验证了所提出的概化工作模式。

A novel generalization of boost-type PFC topologies with multiple switching cells connected in series and parallel

In this paper a novel generalization of boost-type Power-Factor-Correction (PFC) topologies with multiple switching cells is proposed. It is based on parallel connection of two or more series PFC topologies by means of one or more coupled-inductors. Using the minimum number of active power devices as optimization criterion and Stacked-Flying-Capacitors (SFC) multilevel principle, the series PFC topologies are also generalized for more than five voltage levels. The operation mode of the proposed generalization is verified by numerical simulations both for 7L-series PFC and 9L-series-parallel PFC three-phase topologies.
