摘要

混合型模块化多电平换流器(MMC)桥臂中既包含半桥子模块，又包含全桥子模块，原有载波移相调制方法并不适用。文中在分析子模块混合型MMC拓扑结构工作原理及其调制方法的基础上，提出了一种适用于混合型MMC且带电容电压均衡策略的改进载波移相调制方法。在PSCAD/EMTDC中搭建了详细仿真模型，仿真结果证明了该调制策略的有效性。

Abstract

Arms of a hybrid modular multilevel converter (MMC) consists of both half bridge submodules (HBSMs) and full bridge submodules(FBSMs). The original phase shifted carrier (PSC) modulation method is just inapplicable. Based on an analysis of the working principle of hybrid MMC topology and its modulating method

a PSC modulating method with capacitor voltage balancing strategy for hybrid MMC is proposed. Finally

a detailed simulation model based on PSCAD/EMTDC is developed. The modulating method proposed is proved effective by simulation results. This work is supported by Guangdong Provincial Special Fund for Introducing Leading Talents (No. SEPRI-K131003).
