Abstract

In the multi-phase interleaved converter with peak current mode control, current imbalance is measured when inductors of converter module are not exactly identical. In this paper current-sharing controller is proposed to balance phase current of converter modules. It also is designed to have good transient response. Proposed method implemented the 2-phase and 4-phase interleaved boost converter with imbalanced inductance. Experimental results verify the performance of Current share during the transient state of converter.

다상 교호 컨버터에서 인덕턴스가 불일치 할 때 첨두전류 제어기를 사용하는 경우에 각 상의 평균 전류는 동일하지 않다. 본 논문에서는 각 상의 인덕턴스가 불일치한 경우에 첨두전류 모드에서 평균전류가 동일해지는 전류분배 제어기를 제안한다 제어기는 과도상태에서도 전류의 평형이 잘 이루어질 수 있도록 설계한다. 제안된 방법을 2상과 4상 교호 승압컨버터에 적용시켰으며, 실험 결과를 통해 인덕턴스가 불일치한 경우에도 첨두전류 모드에서 전류평형이 잘 이루어짐을 보인다.
