Abstract

A recently proposed active input current shaper (AICS) is used to turn a conventional buck converter into a single stage AC-to-DC power converter that complies with IEC 1000-3-2 regulations with high efficiency, fast transient response and low cost. This topology is used in this paper to design an online battery charger with no galvanic isolation. This solution is a very simple one and only implies slight changes to the conventional topology. Besides, efficiency is high and the size increase is small, all of which are obtained at a very low cost.

带有源输入电流整形器的交流-直流降压变换器
最近提出了一种主动输入电流整形器(AICS),用于将传统降压变换器转变为符合IEC 1000-3-2标准的单级交直流功率变换器,具有高效率、快速瞬态响应和低成本的特点。本文利用这种拓扑结构设计了无电隔离的在线电池充电器。该解决方案非常简单,只需要对传统拓扑进行轻微更改。此外,效率高,尺寸增加小,这些都是以非常低的成本获得的。
