병렬 부하를 가지는 DC 배전 시스템에서 Voltage Bus Conditioner의 가변 구조 제어기 설계

초록

A DC distributed power system (DPS) is used in various high-tech industries. In particular, DC DPSs include many constant power loads or large pulsed loads with short duty ratio which can affect the stability of the system. A voltage bus conditioner (VBC) is used to mitigate the voltage transients on the bus. In this paper, the VBC utilizes the reduced capacitive storage. The DC DPS has parallel loads. A sliding mode controller(SMC) is designed for the VBC. The simulation results by PSIM are presented for validating the proposed control technique.
