与传统的交流输电相比，高压直流输电系统正变得越来越受欢迎。高压直流电压源换流器（VSC）可以提供优于传统高压直流电流源换流器拓扑的优点，因此，随着高压直流输电的发展，预计HVDC-VSC将得到进一步开发。本文介绍了一种最近提出的模块化多电平（M2 C）混合电压源换流器的低损耗操作的HVDC市场。该变换器的操作被描述为用于AC-DC功率传输和无功功率补偿。模拟结果和估计的半导体损耗的基础上提出的建议，为20兆瓦的演示样机。（5页）
HVDC transmission systems are becoming increasingly popular when compared to conventional AC transmission. HVDC voltage source converters (VSC) can offer advantages over traditional HVDC current source converter topologies and as such it is expected that HVDC-VSCs will be further exploited with the growth of HVDC transmission. This paper demonstrates the low loss operation of a recently proposed modular multilevel (M2C) hybrid voltage source converter intended for the HVDC market. Operation of the converter is described for AC-DC power transmission and reactive power compensation. Simulation results and an estimation of semiconductor losses are presented based on proposals for a 20 MW demonstrator prototype. (5 pages)
