Abstract

This paper presents a technique to reduce the low frequency ripple voltage of the dc output in a BIFRED converter with a small-sized energy storage capacitor. The proposed pulse width control method can be effectively used to suppress the low frequency ripple appeared in the dc output and still shows generally good performance such as low THD of input line current and high power factor. Using the small-sized energy storage capacitor, it has better merits of low cost and small size than a conventional BIFRED converter. The proposed technique is illustrated its validity and effectiveness through simulations.
