Analysis of Switching Frequency Characteristics of Single-switch High Step-up DC-DC Converter with Three-winding Coupled Inductor

Abstract

Recently, high step-up DC-DC converters have been widely used in several applications. Previously, we proposed a novel high step-up DC-DC converter, which consisted of a single-switch and a three-winding coupled inductor. Our previous report only highlighted the CCM operation and steady state principle of the proposed converter. This study aimed to investigate the switching frequency characteristics including the CCM and DCM operations of the proposed converter.
