High‐frequency single‐switch PFC with frequency‐modulation controlled class‐E2 converter

IET Power Electronics, 2021
This paper presents a single‐switch zero‐voltage switching (ZVS) power‐factor correction converter based on the class‐E2 converter at 1 MHz switching frequency. A design method for ensuring the ZVS for the entire line‐voltage period is proposed.
