The fundamental configuration of the main circuit of series power quality compensator is proposed and its design scheme of the main circuit is analyzed based on the development of an experimental prototype. Moreover, the configuration, operation mode and control strategy of inverters are presented. The influence of the series transformer and output filter on the capacity is also discussed and the advantages and disadvantages of the three styles of DC energy are compared. The reference of the optimization circuit design for some devices is offered.
