Abstract

This paper presents the detailed modelling and experimental verification of a proposed three-phase Improved Switched Inductor Z-Source Inverter (ISL ZSI). Because of the limitations of classical Z-source inverter, the ISL ZSI has been proposed to increase the conversion voltage gain, to reduce the voltage stress on the capacitor of Z-network and to remove the inrush current. In this paper, a detailed model of the proposed inverter is presented and analyzed. PWM control and relationships of voltage gain and voltage stress versus modulation index are explained. Then, a detailed loss model for the ISL ZSI is derived. Simulation results are obtained to confirm the proposed topology and its loss model. Then, a prototype of 250 W is presented and experimentally tested. A good match is obtained for calculation, simulation and experiment.
