Abstract

본 발명은 전력 변환 장치의 병렬 연결에 있어서, 순환 전류를 억제함으로써 그 효율을 개선하고 용량 증대의 편리성을 제공하는 전력변환장치에 관한 것이다. 전력 변환 장치를 병렬 운전함에 있어 발생하는 순환 전류는 크게 저주파 순환 전류와 고주파 순환 전류로 나눌 수 있다. 저주파 순환 전류는 컨버터 사이에서 발생하는 불균형에 의해서 발생하게 되고, 고주파 순환 전류는 PWM 방법을 사용하였을 때 발생하게 된다. 본 발명은 전력 변환 장치를 병렬 운전함에 있어 발생하는 순환 전류를 해결하기 위한 것으로서, 역전류 방지부 또는 멀티 인덕터를 사용하는 전력 변환 장치에 대해 제공한다.
