본문

본 논문에서는 Cascaded H-bridge multilevel inverter (CHMI)의 IGBT 모듈 수명 연장 및 신뢰성 향상을 위한 DPWM (Discontinuous pulse-width modulation) 기법을 제안한다. CHMI는 모듈형 구조를 갖는 전력변환장치로서 다수의 IGBT 모듈로 구성된다. IGBT 모듈은 전력반도체 스위치로서 전력변환장치의 주된 고장요인 중 하나이다. 본 논문에서 제안하는 DPWM 기법은 스위칭 손실을 저감함으로써 CHMI를 구성하는 IGBT 모듈의 수명을 연장한다. 또한 Rotation 기법을 통해 IGBT 모듈 내 IGBT 스위치 간의 수명을 균등화하여 CHMI의 신뢰성을 향상시킨다. 제안하는 기법의 성능은 시뮬레이션 결과를 통해 검증한다.
