Analysis and Evaluation of Modular Multilevel Converters for DC-DC Solid-State Transformer Based on Different Operating Conditions

In modular multilevel converter (MMC) based solid-state transformer (SST), the MMC dominates total volume and power loss. The loss and volume of MMC are influenced by various factors, such as operating frequencies, waveforms of ac-link voltage, numbers of submodules, as well as modulation methods. T...
