Implementation of Dual Active-Clamped Step-Up DC-DC Converter with Reduced Voltage Stress For Low-DC Renewable Energy Sources

J. Sivakumar, V. SenthilNayagam

Abstract


This project proposes a dual active-clamped step-up DC-DC converter. The proposed converter has the dual active-clamping circuit with single connected transformer. Compared to the previous active-clamped step-up DC-DC Converters, the voltage stresses of the semiconductor devices is further reduced in the proposed converter. The proposed converter has low switching power losses and high power efficiency. The use of single transformers gives a low-profile design for the step-up DC-DC converter for low-DC renewable energy sources like photovoltaic module and fuel cell. The performance of the proposed converter is verified from 600 W (400 V / 1.5 A) experimental prototype circuit for 50 V photovoltaic module voltage.
