Analysis and Design of Enhanced Gain Two‐Switch Modified DC–DC Converter

This paper presents a two‐switch–modified DC–DC converter (TSMC) using voltage multiplier cells exhibiting enhanced voltage gain under reduced duty cycle, continuous input current, and minimized voltage stress across the switches. The proposed converter will be suited for renewable energy applications due to these enhancements. The steady‐state analysis of TSMC is validated under continuous conduction mode (CCM) and discontinuous conduction mode (DCM). A steady‐state analysis is conducted to investigate the operation of the converter, and its components are designed by adhering to a proper design procedure. The small‐signal modelling of the proposed converter is also performed to verify the stability of the converter using the pole‐zero positions. The TSMC is compared with the existing converters to prove its potential. The theoretical analysis of the proposed converter is validated using MATLAB simulation and experimental prototype results. The proposed converter is designed for a 100‐W power rating to boost the voltage from 20 to 200 V at a 0.54 duty cycle with a 50‐kHz switching frequency. Furthermore, the efficiency and power loss investigation are also discussed in this paper.
