摘要
大功率三电平交-直-交变流器由于具有优良的性能,得到越来越广泛的应用。本文首先介绍了7.5MVA大功率三电平IGCT交-直-交变流器的结构和控制系统,然后对IGCT元件试验、变流器系统仿真及试验等进行介绍。试验结果表明,该变流器达到了设计要求,具有良好的性能。
Large power three-level AC-DC-AC converters have excellent performance, and they are widely used in many fields now. In this paper, the structure and control system of the 7.5 MVA large power three-level AC-DC-AC converter is given. Then, test of the IGCT device is introduced, and the system simulation and experiment of the converter is given. The experimental results show that the converter reaches the design requirement and has excellent performance.
