A pre-charging strategy based on composite frequency control for a modular multilevel DC transformer
Modular multilevel DC transformers(MMDCTs) have become a research focus in DC grids with different voltage levels based on their advantages of strong expansibility and high voltage levels. It is necessary to apply pre-charging control to avoid inrush currents generated by the charging of the capacit...
