Design and Implementation of A Transformerless High Step-Up DC-DC Converter Based on Conventional Boost Converter and Voltage Multiplier Cells

Abstract

In this study a transform-less high step-up converter has been proposed. The topology of the proposed converter has been built up based on the conventional boost converter and has been modified by two voltage multiplier cell. The mentioned converter has been designed for the continuous current mode. The voltage ratio of the proposed converter has been extracted for both ideal and non-ideal mode. The non-ideal voltage ratio of the proposed converter has been compared with other high step-up DC-DC converters. Moreover, the practical voltage ratio of the converter has been extracted and compared with the result of the relation of the non-ideal voltage gain. Finally, the simulation results have been extracted and compared with experimental results. The PLECS is the simulation engine which has been used in this study.
