Abstract

The modular multilevel converter (MMC) is now very popular in high power high voltage applications. However, the bulky capacitor employed in each submodule (SM) accounts for more than half of the total volume and weight of the entire system. This prohibits further system level integration due to space and weight restrictions. To tackle this issue, a virtual infinite capacitor (VIC)-based active SM (VIC-SM) configuration is presented in this paper. Special attention is given to the charge control of an MMC with a low number of SMs. The concept is verified in the MATLAB/Simulink environment with a downscaled case study of a 50W 400VDC/110VAC 11 levels single phase MMC. We show that the VIC-SM can reduce the SM capacitance by 60% with sufficient safety margin.
