一种具有轻载优化控制策略和软开关能力的重构型图腾柱PFC整流器

This article presents a reconfigurable totem-pole bridgeless power factor correction converter employing an auxiliary circuit and a simple control scheme to achieve high efficiency. Under light load condition, instead of delivering the energy through the main switch, the proposed converter utilizes only the auxiliary switches by using a different control scheme. Since the auxiliary switches have m...
