基于准周期系统摄动理论的模块化多电平变换器建模与能量平衡控制

The most common modular multilevel converter (MMC) balancing solution uses the circulating current to generate additional powers in conjunction with the terminal voltages including the common-mode voltage, relying on distinct frequencies. Usually, the energies affected by each frequency component are identified assuming constant amplitudes, which neglects the inevitable impact on the other energie...
