XU Kui, MA Xiaohong, HU Pengfei, et al. Analysis of Sub-module Capacitor Voltage of Full Bridge MMC-based Deicing Technology[J]. 2021, 47(2): 596-602.DOI:
The sub-module capacitor voltage of a DC deicing divice based on the full bridge MMC was analyzed and investigated in this paper. Moreover
a relation equation is derived to describe the relationship between the voltage fluctuation of sub-module DC side and the DC deicing circuit
voltage modulation raio
the dc current
and the capacitance. Based on this equation
the solution of the maximum voltage fluctuation of the sub-module capacitor is derived which serves as an effective tool for the design calculation of an MMC deicer. The correctness and accuracy of the derived equations are validated through PSCAD simulation and experiments.
