Adaptive Modulation Strategy for Modular Multilevel High-Frequency DC Transformer in DC Distribution Networks

Abstract: The modular multilevel high-frequency DC transformer (MDCT) plays an important role in the bus connection, voltage conversion, power transmission and electrical isolation in the DC distribution networks. During practical operation, the mismatch between high-frequency-link (HFL) voltages and HFL transformer voltage ratio caused by the variation of DC bus voltages occurs, resulting in the increased reactive power, larger current stress and decreased efficiency in MDCT. To solve this problem, an adaptive modulati… Show more
