摘　　要：对一种新型的多级注入式电压源型变流器进行分析和研究。它可以进一步消除谐波,解决可串接开关技术的动态电压平衡问题,大大提高了高功率变流器的运行效率和可靠性。同时它结合了二极管嵌位多级变流器、多级注入式VSC以及软开关的优点。它可以作为一个理想的STATCOM装置使用,在仿真中,使用了EMTDC-PSCAD进行了稳态、动态的详细分析。证实了它能大大减小谐波含量,降低开关损耗。This paper discusses a new concept of multi-level reinjection VSC, its main purpose being a further reduction of the harmonic content, a solution of dynamic voltage balancing for direct series connected switching devices and an improvement of high power converter efficiency and reliability. In simulation, EMTDC-PSCAD is used to illustrate the steady state and dynamic performance in details. The VSC is showed to be a ideal solution for the statcom application. It is showed that this configuration provide very low distortion levels and reduced switching losses.
