Experimental studies on a three phase improved switched Z-source inverter

This paper presents an experimental verification of the Improved Switched Inductor Z-Source Inverter (ISL-ZSI). The ISL-ZSI has been proposed to overcome the limitations of classical Z-Source Inverter (ZSI) such as lower voltage gain, higher capacitor voltage stress of Z-network and huge inrush current that appears in the case of traditional ZSI. In this paper, different aspects will be presented and analysed such as the PWM control, relationships of voltage boosting gain versus modulation index, voltage stress versus modulation index and output voltage/current. Those important points will be analyzed in detail and verified by simulation and experimentally.     «
