부하불평형 해소를 위한 축소형 보상설비 개발

Development of the down-scaled compensator for the solution of unbalanced load

This paper proposes analysis on new equipment for power quality in electric railway. The proposed equipment consists of series inverter and parallel inverter. Each inverter is connected by capacitor as dc link. This structure can be compensated for active and reactive power in catenary through transformer.
