본 논문에서는 낮은 전압 변조 지수(modulation index, MI)영역을 고려한 3-레벨 hybrid active neutral point clamped (HANPC) 인버터의 계통 필터 설계 기법을 제안한다. HANPC 인버터는 기본파 주파수와 같은 스위칭 주파수로 동작하는 silicon IGBT 소자와 삼각파 주파수에 따라 높은 스위칭 주파수로 동작하는

silicon carbid MOSFET 소자로 구성된다. 기준에 따른 출력 품질을 만족하기 위해 대용량 L-필터를 사용하면 동특성 저하 및 전압 강하 현상이 발생한다.

이러한 L-필터의 단점을 보완하기 위해 동특성 및 고조파 저감에 유리한 LCL-필터를 설계한다. 기존 LCL-필터 설계 기법은 MI에 따라 변화되는 필터 양단

전압을 고려하지 않고 설계되어 낮은 MI 영역에서 목표 THD를 만족시키지 못하는 단점이 있다. 본 논문에서는 상전압 및 계통 전압을 분석하여 낮은

MI에서도 목표 THD를 만족하는 필터를 설계한다. 시뮬레이션을 통해 제안하는 기법의 성능 및 타당성을 검증한다.
