Hi-Bridge Resonant Soft-Switched Boost Converter
This paper presents a high step-up DC-DC converter. The proposed converter comprises of a boost converter with
an auxiliary switch and resonant circuit. The resonant circuit consists of a resonant inductor, two resonant capacitors, two
diodes and an auxiliary switch. These resonant components make partial resonant path for the main and auxiliary switch to
perform soft switching under the zero voltage condition using the resonant circuit. The proposed boost converter improves
the whole system’s efficiency, by reducing the switching losses. The proposed soft switching boost converter has been
simulated in PSIM software. The performance of the proposed boost converter is verified through the theoretical analysis
and simulation results.
