模块化多电平变换器中多个子模块的三相任务剖面仿真器

This article proposes a highly efficient mission profile emulator (MPE) for submodules (SM) in modular multilevel converter (MMC), with respect to its basic circuit topology, control method and design. By using a common three-phase dc–ac power converter, as well as some analytical equations of MMC, the proposed MPE is capable of emulating operating conditions of multiple SMs in the MMC system.
