| Abstract: | In order to overcome the shortcomings of traditional generalized active power filter （GAPF） ,a GAPF based on modular multilevel converter （GAPF/MMC） was proposed which has higher waveform quality and voltage rating. Its topology, operating principle, control method and modulation strategy were described. The balancing method of capacitor voltages of sub modules was presented. The experimental results show that GAPF/MMC can effectively reduce the harmonic content of output voltage and the capacity and power consumption of system side reactance while realizing comprehensive compensation, and is suit able for application in high voltage and power field. |
