Abstract
This paper investigates the performance analysis of the Modified-Z-Source Inverter with a simple voltage boost control method. The Z-Source network provides an efficient method of converting electricity in grid-connected solar applications, requiring only one step to fulfill the requirements. Nevertheless, high voltage stress and high voltage rating capacitor problems plague the Z- source inverter. In order to overcome these problems, a customised Z-network that maintains the same shoot-through duty ratio as a Z-source inverter is utilised to provide high boosted voltage. This research compares the performance of the modified Z-source inverter with the Z-source inverter using MATLAB.
Keywords: Z-Source Inverter, Modified-Z-Source Inverter, Voltage gain
