Abstract

In this paper a 500 W (50 V@10 A) forward converter is presented, which is part of a battery charger. An auxiliary resonant circuit was added to the basic forward converter, implementing the zero-voltage-transition (ZVT) technique for the main switch. The switch employed by the auxiliary circuit operates under zero-current-switching (ZCS) conditions. The overall efficiency improvement goes from about 2% at light load, to about 5% at full load.

一个500w (50 V@10 A) ZVT正激变换器

本文介绍了一种500w (50V@10 a)正激变换器，它是电池充电器的一部分。在基本正激变换器上增加了辅助谐振电路，实现了主开关的零电压转换技术。辅助电路使用的开关在零电流开关(ZCS)条件下工作。总体效率从轻载时的2%提高到满载时的5%。
