Improved Symmetric Switched-Inductor/Capacitor Quasi Z-Source Inverter with Ability Uplifted-Boost

چکیده مقاله

This paper proposes a topology of switched-inductor/capacitor quasi z-source inverter (SIC-qZSI) based on the classic qZSI. This topology is symmetric with a high boost factor in the low duty cycle and high modulation index, the low voltage stress on the capacitors, and the low current of the inductors and the input source. In addition, the current of all inductors and the input current are equal, and the voltage across all the inductors, as well as the voltage across all diodes, are equal. The performance of the proposed topology is confirmed with MATLAB/SIMULINK software and the simulation results and obtained relations are certified by using a prototype of the proposed inverter.
