| Abstract |
This paper discusses the design of a high efficiency isolated boost converter for low voltage applications, including DC micro grid systems, fuel cell, and battery applications. The AC resistance factor and the leakage inductance of an isolating transformer is improved based on a better core selection. A comparative analysis of copper foil and Litz windings with interleaved configuration is also presented. The integration of copper foil transformer in the converter increases the overall efficiency of the converter. The high efficiency of the converter is further achieved by using repetitive avalanche rated MOSFETs for unclamped switching and Schottky didoes for fast switching action. The experimental results verify the high efficiency of the transformer and the designed converter. |
