A novel interleaved and isolated buck converter with high voltage ratio

This paper presents a novel interleaved and isolated DC to DC buck converter with high voltage ratio. The converter consists of a half-bridge converter and a forward converter which are connected in parallel with a common load. As being one of interleaved DC to DC converters, it has smaller output current ripples within wide duty ratio, and it also has isolated input/output parts and higher voltage ratio due to applying transformers. So the converter presented in this paper is an isolated DC to DC buck converter with advantages of wide duty ratio, small output current ripple, and high voltage ratio. Simulation and experimental results are shown to verify the performance of the proposed converter.
