摘要
在大功率开关电源领域,PFC电路整流桥堆的损耗成为整个开关电源重要的损耗之一。为了减少桥堆在开关电源上的损耗,业界提出了很多针对无桥堆PFC的结构。文中主要通过Matlab Simulink仿真无桥PFC结构的工作原理,对无桥PFC设计的可行性进行指导。
In the field of high-power switching mode power supply, the loss of PFC circuit bridge rectifier becomes one of the important losses of the whole switching power. In order to reduce the bridge loss in the switching power, the industry proposed a lot of bridgeless PFC structures. This article carried on simulation the working principle of bridgeless PFC structure by matlab simulink, providing guidance for the feasibility of the design of bridgeless PFC.
