High Frequency Transformer Isolated Quasi Z-Source Cascade Multilevel Inverter

In this paper, a new structure of HFTI-qZS-CMI has been proposed. The proposed structure is capable of generating high-voltage for medium to high power applications. By adding a switch, a capacitor and a high-frequency transformer and also eliminating an inductor from each qZS-CMI cell, the HFTI-qZS-CMI structure will be created. Using the high-frequency transformer in the proposed structure, l...
