Analytical Approach of Circulating Current Mitigation Effect using Coupled Inductor in Parallel Interleaved Converters

병렬 Interleaved 컨버터에서 일반화된 순환전류 제어 방법

In this paper, the coupled inductor with three branches in two interleaved converter are analyzed to effectively suppress the high frequency circulating current since the circulating current controller cannot mitigate the high frequency circulating current. As a result, the novel averaged model including the coupled inductor with zero sequence components is developed for reducing the low and high frequency circulating current simultaneously.
