Abstract

The performance of 4-switch 3-phase inverter(: FSTPI) which replace two switches of 6-switch 3-phase inverter(: SSTPI) is mainly affected by the compensator unbalanced voltages and output voltage control method. This paper proposes a DC offset current injection method to compensate the capacitor unbalanced voltages for FSTPI. A simplified SVPWM method which can be applied to FSTPI is also proposed. The validity of the proposed methods is verified by simulation and experiment using SPMSM.

6스위치 3상 인버터(SSTPI)의 한 상을 스위치 대신 커패시터로 대체한 4스위치 3상 인버터(FSTPI)에서 커패시터 전압의 불평형으로 인한 출력 전압의 오차를 보상하는 방법과 전압 제어 방법은 FSTPI의 성능을 결정짓는 중요한 요소이다. 본 논문에서는 DC 오프셋 전류 주입 통한 FSTPI의 커패시터 전압의 불평형을 보상하는 새로운 방법과 FSTPI의 새로운 전압 제어 방법인 간략화 된 SVPWM을 제안한다. 제안된 방법은 FSTPI로 SPMSM를 구동하는 시뮬레이션과 실험을 통해 그 타당성을 검증하였다.
