摘要
模块化多电平变换器(MMC)是一种具有广阔应用前景的多电平拓扑。论文首先推导了MMC桥臂功率的数学模型,然后提出了一种适用于MMC子模块的有源功率解耦方案,并设计了适当的控制策略来抑制子模块的纹波功率。最后设计了一台额定功率为400W的实验样机,通过实验验证了该方案的可行性。
The modular multilevel converter(MMC)is a promising multilevel topology.This paper firstly introduces the mathematical expression of MMC arm powers is derived,and then an active power decoupling scheme suitable for MMC submodule is proposed,and an appropriate control strategy is designed to suppress the ripple power of the submodule.Finally,an experimental prototype with rated power of 400W is designed.Experimental results was made to verify the feasibility of the control strategy.
