| 摘要: |
| 为提高链式结构DSTATCOM的补偿性能和可靠性，基于电力电子积木（PEBB）概念设计了其“即插即用”型基本功率单元——基于H桥逆变器的换流模块（HCM）。介绍HCM的主电路主要设计选型，并针对额定容量278 kW、电流600 A的HCM进行了结构和散热设计。为提高HCM工作灵活性和抗干扰能力，基于复杂可编程逻辑器件（CPLD）设计模块控制器，实现对模块控制、检测和采样，采用专用驱动核芯片设计驱动电路工作，完善保护并提高模块稳定性。介绍了用于HCM测试的实验平台，在10 kV／± 3 Mvar的DSTATCOM工业样机上运行所设计的HCM，验证了模块的各部分功能的运行性能和可靠性。 |

| Abstract: |
| In order to improve the compensation performance and reliability of cascaded multilevel DSTATCOM，a plug-and-play HCM（H-bridge based Converter Module） as the basic power unit is designed based on the concept of PEBB（Power Electronics Building Blocks）. The type selection for the key devices in its main circuit is introduced and its structure and heat sink are designed for rated output current of 600A and nominal capacity of 278kW. The module controller for the control，sampling and detection is designed based on the CPLD（Complex Programmable Logic Device） to improve its flexibility and anti-interference ability and the drive circuit is designed based on the dedicated driver chips to provide the protection and improve the stability. The experimental platform is introduced，and the performances and reliability of the designed HCM operating in a 10 kV／±3 Mvar industrial prototype of DSTATCOM are verified. |
