The Use of Tapped Inductors and Autotransformers in DC/DC Converters Shown for the SEPIC
Authors: Felix A. Himmelstoss, Helmut L. Votzi
Abstract: Studying the function of DC/DC converters is an important topic when organizing a course in Power Electronics. The use of tapped inductors or autotransformers changes the behavior of the converter and also the stress of the semiconductors. In this paper, a simple way to teach these converters is shown and demonstrated for two variants of the well-known SEPIC converter. Suggestive drawings and simple calculations and simulations are used to demonstrate the operation of the converters. The large signal and the small signal models for one variant are calculated.
