Abstract

This article proposes a new high step up DC-to-DC converter with single active switch based on voltage lift technique and voltage multiplier. The N-stage cascaded quadratic boost converter is used by replacing its inductor with a voltage lift cell to improve the voltage gain with an average duty ratio. In this work, the voltage multiplier cell can double the voltage conversion ratio making the voltage stress on the switching device half the output voltage. The proposed converter also has small input and output current ripple, and it has a simple structure with a higher power density and flexible controllability. Theoretically, the input voltage can be increased by the ratio of 32 at a 0.5 duty ratio reducing the voltage stress on the device by 50% of the output voltage providing higher voltage gain and output power than its counterparts. Simulation results are provided using MATLAB/Simulink to validate the proposed topology.
