Abstract

In this paper, maximum boost discrete PWM(DPWM) method of Z-Source Inverter(ZSI) is proposed. In general, a DPWM method is used to reduce the switching losses of the inverters and increase the efficiencies. The maximum boost PWM method of Z-Source Inverters is combined with the DPWM method. The proposed Maximum boost DPWM of ZSI is analyzed and it shows how to reduce the switching losses of ZSI. An experimental system has been built and tested to verify the effectiveness of the proposed method.

본 논문에서는 Z-소스 인버터의 최대승압 불연속 PWM 방법을 설계하였다. 일반적으로 불연속 PWM 방법은 스위칭 손실을 줄이고, 효율을 향상시키기 위하여 사용되어 왔으며 본 논문에서는 기존에 연구되었던 Z-소스 인버터의 최대승압 PWM 방법과 함께 불연속 PWM 기법을 결합하여 적용함으로써 전체 효율을 향상시킬 수 있었다. 제안된 방법은 실험을 통하여, 기존의 PWM 방법들과의 효율을 비교함으로써 효용성을 입증하였다.
