English Abstract

Three-winding coupled inductor structures have gained popularity in high-voltage-gain dc–dc converters. This cell allows generating an infinity of topologies. However, there are no well-established methods for synthesizing these types of converters. In this sense, in order to contribute and create a simple synthesis and generation of high-voltage-gain converters, this article presents a family of ...
