병렬 부하를 가지는 DC 배전 시스템에서 Voltage Bus Conditioner의 PI제어기 설계

초록

DC power distribution system(PDS) is widely used in electric vehicle, aircraft and regenerative system, etc. However DC bus instabilities may be occurred by the interaction between the input filter and the constant power load. Moreover, bus instabilities in the DC PDS with parallel loads may be more severe. Thus, a Voltage Bus Conditioner(VBC) can be used to alleviate the bus transients on the DC bus. In this paper, the VBC with the reduced capacitive storage is used to damp the severe bus transients and the VBC is controlled the PI compensator. The simulation results by PSIM showed the validity of the proposed systems.
