【 摘 要 】

The paper deals with a new family of high boost voltage inverters which improve upon the conventional trans-Z-source inverter and trans-quasi-Z-source inverters. The improved trans-Z-source inverter (ITZI) that provides continuous input current and a higher boost voltage inversion capability. In addition the improved inverter can suppress resonant current at start up, which might destroy the device. In comparison to the conventional trans-Z-source and trans-quasi-Z-source inverters, for same transformer turn ratio, input and output voltages, the improved inverter has a higher modulation index with reduced voltage stress on the DC link, lower current stress flow on the transformer windings and diode, are validated by simulating (ITZI) in MATLAB/SIMULINK.
