The PI control of the Voltage Bus Conditioner for the improvement of the Power Quality in the DC Power Distribution System with multiple parallel loads

다중 병렬 부하를 가지는 DC 배전 시스템에서의 전력 품질 향상을 위한 Voltage Bus Conditioner의 PI 제어

A DC Power Distribution Systems(DC PDS) are widely used in telecommunication system, electric vehicle, aircraft, military system, etc. In the DC PDS, DC bus voltage instability may be occurred by the operation of multiple loads such as pulsed power load, motor drive system, and constant power loads. To damp the transients of the DC bus voltage, the Voltage Bus Conditioner(VBC) with the PI compensator is used. In this paper, the validity of the proposed VBC system is verified by PSIM simulation package.
