Half‐bridge flipped‐gamma Z‐source inverter with high voltage gain

Abstract

SummaryIn this paper, a new coupled inductor Z‐source inverter is proposed. The proposed topology can increase the boost factor value by increasing the number of turns ratio values. The proposed inverter is completely analyzed, and the related equations to the voltage and current of the used elements and boost factor are obtained. In addition, the values of the capacitors and inductors are designed to have a better performance based on the considered boost factor and input voltage level. Following, the proposed inverter is compared with several related topologies to determine the advantages and disadvantages of the proposed inverter. Finally, the accuracy performance of the proposed inverter is verified through results on experimental prototype.
