The fusion of the converter multilevel technology and the current injection technology are used to reduce the switch frequency of power devices in the main circuit, so that the switching loss is reduced. Pumping circuit features inherent in the zero current circuits provide a possibility for using thyristors in the main circuit, and provides a potential, realized soft switch. The STATCOM model is simulated in PLECS, and the results show that the reactive power can be flexibly controlled in full range. Sampling waveforms of the experimental device verify that flexible power regulation can be
