The Uplifted-Boost Switched-Inductor/Capacitor Quasi Z-Source Inverter: A Proposed Structure

In this article, a new structure of the switched-inductor/capacitor quasi Z-source inverter (SLC-qZSI) is proposed that has a high boost factor in a high modulation index to provide an improved quality output voltage. Additionally, this structure has features such as equal and low voltage stress on capacitors of SLC cells and diodes, identical current ripple for the source and all inductors, a low shoot-through (ST) current in the main switches, and a continuous input current with no startup inrush current. The performance of the proposed structure is confirmed using MATLAB/Simulink software, and the simulation results are validated by using a prototype of the proposed structure.
