Sub-module Capacitance Design of Modular Multilevel Converters
摘要
Abstract
In this paper, the power characteristics of the arm in the Modular Multilevel converter (MMC) was studied, and the mathematical equation of the instantaneous power of the arm and the DC component of the arm current were acquired. By studying the equivalent circuit of the capacitor charge circuit, the mathematical equation of the equivalent charge current and capacitor AC voltage component were acquired. Based on the mathematical equation of the capacitor AC voltage component, the relationship of magnitude of B with modulate ratio and power factor angle were acquired. Furthermore, the mathematical equation of the magnitude of capacitor AC voltage component were worked out and the design approach of the sub-module capacitor were put forward. The simulation results show the accuracy of the mathematical equation of capacitor AC voltage component and the design approach of the sub-module capacitor.关键词
