Analysis and Development of Weinberg Converter with Fault Tolerant Feature

摘要

Space applications demand power converters of high reliability, fault tolerance, high power to volume and weight ratios. Weinberg converter is one such topology having these features built in. This topology can also be called as, coupled inductor fed push-pull converter. It provides continuous current at its output, which reduces the requirement of filter bank capacitors at the output stage. In this research article, isolated Weinberg converter working principle is explained with large signal and state space analysis. Also building of working bread-board model and its test results are dealt. The paper brings out the inherent fault tolerant feature of the Weinberg converter.
