Using off-the-shelf computers and FPGA boards, the converter, including the 6 valves, 6 arm inductors and the transformer, is simulated with a time-step of 450 ns. Such a small time-step is required to ensure high accuracy when applying gating signals but also when observing fault conditions. Simulation stability is demonstrated for normal and faulty operation modes.
这篇论文介绍了对一个有512电平的MMC的仿真结果。使用现成计算机和FPGA板，这个包含6个阀和6桥臂电感和变压器的换流器被以450ns级步长进行仿真。这样短的步长是为在使用门口信号和观测故障情况时保证精确度。仿真稳定性在正常和故障操作下进行了演示。
