摘要

本文提出了一种针对中、低输出功率的低外形适配器的主动高密度设计。采用同步整流的高频准谐振反激变换器，与目前最小的产品级设计相比，整体体积减小21%。提出了详细的设计思路，并通过19V/3.42A的实验通用输入脱机反激样机验证了其性能。

High frequency high density low profile adapter

This paper presents an initiative high density design for low profile adapter with medium or low output power. The high frequency quasi-resonant flyback converter with synchronous rectification helps to decrease the whole volume 21% compared with the current smallest product level design. The detailed design consideration is presented and performance is validated by an experimental universal-input off-line 19V/3.42A flyback prototype.
