本文講述了一個基於FAN4800 連續PFC 前端的雙管正激電源的功率級設計。回顧了這種電源的設計選擇。討論的實際課題包括功 率器件選型，電磁設計，佈局和電磁干擾 (EMI)，目的在於幫助工程師加速並改善其設計。(This article about a front-end based on the FAN4800 PFC consecutive two-transistor forward power stage power supply design. Review this power supply design options. The actual topics discussed include the selection of power devices, electromagnetic design, layout, and electromagnetic interference (EMI), designed to help engineers to speed up and improve its design.)
