This study assesses the performance of the quasi Z-source modular multilevel converter (qZS-MMC) in voltage boosting mode for medium voltage applications while also taking into account the design process and modulation of the device. The qZS-MMC is a modular multilevel converter (MMC) that enables the generation of an output voltage greater than the input DC voltage. It is made up of two quasi Z-source networks that are inserted between the two terminals of the DC input source and the DC-link terminals. Based on a mathematical derivation for the internal voltages, currents, and stored energy of the converter, two modulation techniques have been examined. It has been demonstrated that the quasi Z-source circuit gives the qZS-MMC half bridge sub-modules to handle DC-faults. The experimental findings support the effectiveness of the suggested modulation methods and the qZS MMC's capacity to block DC faults. The losses of the qZS-MMC are then contrasted with those of a typical MMC using full bridge sub-modules that also have DC fault capabilities. It has been determined in which range the qZS-MMC is more effective. Additionally, the qZS-MMC can offer a substantial reduction in the amount of semiconductor power devices while maintaining performance.
