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
