Design of dynamic voltage restorer for voltage sag and swell compensation using high-frequency-isolated direct AC-AC converter without commutation problem

Abstract

In this paper, a dynamic voltage restorer (DVR) is presented based on a novel buck type PWM direct ac-ac converter topology. The ac-ac converter used in proposed DVR has no commutation problem because of using switch cell structure and coupled inductors, and therefore, it does not need to sense the input voltage polarity for safe commutation, which saves… (More)
