摘要

一种最新的超结MOSFET应用于硬开关，大功率PFC应用，并与软开关IGBT进行了比较。通过降低导通电阻和增强开关特性，超结MOSFET可以与软开关IGBT竞争。设计了一个1.5kW额定CCM PFC电路，并实现了ZVS逻辑，用于两种配置的性能评估。通过分析开关损耗和传导损耗，讨论了额定功率的极限线。

Power device consideration on high power PFC pre-regulator for optimized design

A latest super-junction MOSFET is applied to hard switching, high power PFC application and compared to soft switched IGBT. With reduced on-resistance and enhanced switching characteristics, the super-junction MOSFET can compete with soft switched IGBT. A 1.5kW rated CCM PFC circuit is designed and ZVS logic has implemented for performance evaluation of both configurations. Limit line of power rating is discussed through analyzing switching and conduction losses.
