YZ Impedance Source Inverter

Abstract

Abstract: In this paper a new topology based on “Z source inverters” is introduced. In the proposed structure, two inductors of the impedance network in conventional Z Source Inverter are replaced by two transformers with three windings. Voltage gain of the new inverter is higher than other Z Source networks with any duty cycle. In order to access high output power quality, the proposed inverter operates at a higher modulation index (near 1). Thereby, stress of switching devices is reduced. The performance of the proposed inverter is verified using the MATLAB/SIMULlNK software.
