본문

본 논문에서는 LCL-필터가 사용된 계통연계 인버터의 공진 전류를 저감하기 위한 개선된 불연속 전압 변조 방식을 제안한다.

기존의 불연속 전압 변조 방식은 전압변조신호가 60도마다 불연속적으로 변하기 때문에 많은 고조파가 발생하며, 이 고조파와

LCL-필터를 사용하는 계통연계 시스템의 공진주파수 대역이 겹치면 계통전류가 공진하는 문제가 발생한다. 제안하는 불연속 전압

변조 방식은 3상 지령 전압의 최대, 최소값을 이용한 오프셋을 전압 변조 신호에 주입하여 불연속적인 부분에 의해 발생하는

고조파를 저감하여, 공진주파수 대역이 겹치게 되었을 경우 발생하는 문제를 방지한다. PSIM 시뮬레이션을 통해 제안하는 불연속

전압 변조 방식의 타당성을 검증한다.
