摘要
文中介绍了交错CRM-PFC的基本原理和基于R2A20112控制器的交错CRM-PFC变换器的设计。临界导电模式(CRM)是一种功率因数校正(PFC)控制方法。交错CRM-PFC允许升压变换器获得180°的相位移和在CRM操作,可使输入和输出电容器上的纹波电流大大地减小。
The basic principle of CRM- PFC and the design of interleaved CRM- PFC converter based on R2A20112 controller are introduced. The Interleaving Critical-Conduction-Mode is a control method for PFC. With Interleaved CRM - PFC, 180° phase shift of boost converter is achieved and the ripple current of input and output capacitor is greatly reduced.
