摘要
模块化多电平变换(Modular Multilevel Converter,MMC)技术以良好的可扩展性、高度模块化和良好电压输出特性正逐渐被推广应用到中高压、大容量电力变换领域。文章首先介绍了MMC技术的主要拓扑结构及其技术特点;然后针对结构特点,提出了以双核微处理器+FPGA为主控制器、以CPLD为从控制器的两级控制系统架构,分别就软硬件设计作了阐述;在实验室的样机验证了控制系统的合理性。
Modular Multilevel Conversion （MMC} with its good scalability, modularization and voltage output characteristics is now gradually popularized in its application to the field of medium and high-voltage ＆ high-capacity power conversion. First, this paper presents its main topological structure and technical features. Then, with respect to its structural characteristics, this paper proposes a two-level control system architecture using dual-core microprocessor ＋ FPGA as master controller and CPLD as slave controller. Their software and hardware designs are explained. The laboratory prototype verifies the reasonability of this control system.
