Current Analysis of Power Devices of the Sub-Module in New Modular Multi-Level Converter

Abstract:

This paper introduced a new modular multi-level converter (MMC), which could enhance the voltage and power level by sub-converter modules in series and was easy to extend to any level of output. Its structure and working mechanism were described.By analyzing the new modular multi-level converter (MMC) working mode, its sub-module four power devices’ current distribution is detailed analysis. It can further guide the choice of the device. The simulation results show that the analysis is correct and effective. It can provide a valid theoretical basis for the choice of the MMC sub-module power devices.
