High Gain Step-Up Dickson Converter with Interleaved Topology for Applications In Renewable Energy

Abstract

Power electronics become a crucial factor on integrating Renewable Energy Sources more into the main grid. Renewable energy resources make the power converters to have a functional and versatile value. Enhancement of the voltage output from the renewable energy systems to a higher level can be achieved using DC-DC Converters. Several converters topologies have been implemented so far and Dickson converter proves to be a high efficient and high performance converter. The Dickson charge pump along with the Interleaved boost stage provides high voltage gain, reduced current ripples and losses in the components. The converter delivers an output with minimal voltage stresses on passive components and semiconductor devices, which enhances the voltage potential for enhancing the maximum power output requirements. The advanced converter topologies also make the integration with distribution systems more beneficial. This project compares Interleaved Boost Converter, Hybrid Nonisolated DC-DC Converter, Modified Dickson Converter with Voltage Multiplier and Bifold Dickson Converter with Five VMC Stages to understand the voltage stresses of different components in the converter, from which the efficiency analysis is made to decide the better converter among the four. The converters are studied in detail by simulation analysis using MATLAB/SIMULINK. Voltage stress and other parameters of each component are obtained and the performance of converters are evaluated. The study is extended to the comparison of each converters . Hardware prototype of the converter is implemented for the validation and testing of the converter on giving a 24V, 4A supply and obtaining a 400V DC outpu
