This paper proposes a static synchronous series compensator based on a multibridge inverter. The proposed system consists of six H-bridge modules per phase which generate 13 pulses for each half period of power frequency. The dynamic characteristic was analyzed by simulations with electromagnetic transients program (EMTP) code, assuming that it is inserted in the 154-kV transmission line of a one-machine-infinite-bus power system. The feasibility of hardware implementation was verified through experimental works using a scaled model. The proposed system does not require a coupling transformer for voltage injection and has flexibility in expanding the operation voltage by increasing the number of H-bridge modules.
