Single Switch High Step-Up Soft-Switching Boost Converter with Coupled Inductor

Abstract

In this paper, a soft-switching boost converter with coupled inductor and a resonant tank is proposed. From this, the switching frequency can be increased without compromising the efficiency of the converter, and consequently the volume, the size and the cost of the components will decrease. To demonstrate the advantage and validate the theoretical evaluation of the proposed converter, such as; simplicity of operation, low components count, single switch, low voltage stress across the components. In this digest, simulation results of $V_{i}=37.4\mathrm{V}, V_{o}=400\mathrm{V}$ and $f_{s}=100\text{kHz}$ are presented.
