用于PFC应用的多通道BCM Boost变换器维持移相的数字闭环控制策略

This paper presents a novel closed-loop digital control scheme to maintain proper interleaving operation of a multi-channel boundary-conduction-mode boost converter used in power-factor-correction applications. The proposed control scheme is suitable for implementation on a low-cost microcontroller. This is made possible by executing the control scheme at a constant sampling rate that is much slow...
