능동전력필터 기능이 추가된 지하철 회생 전력 제어용 인버터에 관한 연구

초록

This paper proposes a regeneration inverter system, which can regenerate the excessive power form the DC bus line to the AC source for traction systems. The proposed regeneration inverter system for DC traction can reduce harmonics which is a characteristic of the AC current source. The simulation was composed as a prototype model [3.7kW]. Finally, it is shown that the inverter can successfully operate in regeneration mode."
