계통연계형 대체애너지 발전시스템을 위한 고펄스 SCR 인터버

In this paper, a new line-commutated SCR inverter for renewable power generation system is proposed. The proposed inverter system includes a 6-pulse SCR inverter and an auxiliary circuit. By the proper operation of the auxiliary circuit, the pulse number of the inverter system is increased and the output harmonic currents are reduced. Analysis, control and simulation for 24 pulse operation of the proposed scheme is presented and the experimental results will be provided in the final paper.
