A Novel Tri-State High Step-Up DC-DC Converter With Coupled Inductor

In this article, a tri-state DC-DC converter is presented, which employs a coupled inductor. The converter proposed herein features a simple design, high voltage gain, minimized voltage stress on switches and diodes, consistent output current, and a shared ground. The mathematical analysis takes into account several factors, including the continuous conduction mode (CCM) of the proposed converters, the voltage stress experienced by semiconductor devices, and the design aspects of components. Following the comparison with various converters mentioned in other references, the results are discussed. Additionally, simulation results of the proposed converter are presented at a power level of 500 watts, using PLECS software, to validate the theoretical arguments put forth in the article.
