A New High Gain Modified Boost Converter for Renewable Energy Application with Closed Loop Control

Abstract

The proposed work presents a new Modified Boost Converter (MBC) for renewable energy applications. The proposed MBC is intended for high voltage applications and operates in the closed-loop control to maintain the desired constant voltage level. The voltage gain of the projected converter is high as compared to the conventional and recently addressed DC-DC converters with few numbers of components. The key features of the MBC are single switch topology which makes the simple control circuitry. By extending the voltage multiplier level, the voltage gain of the MBC can be increased and shows the balanced voltage across each output capacitor. Additionally, proposed converter have the continuous input and output current characteristics. The working principle and mathematical analysis of the MBC is done by considering the components to be ideal. In addition to that, the detailed state-space modeling of the converter is represented along with the controller design. All the analysis is done in Continuous Conduction Mode (CCM). The simulation results validate the feasibility of the proposed converter.
