DC 버스 전압 안정화를 위한 Voltage Bus Conditioner에서의 제어 기법의 연구

초록

A Voltage Bus Conditioner(VBC) may be used to damp the transient bus voltage in a DC Distributed Power System(DC DPS). In this paper, the two kinds of the controls for the VBC are compared with each other. The one of the controls is the sliding mode control and the other is the constant frequency hysteresis control. The performances of sliding mode control and constant frequency hysteresis control are compared. Simulation results by Matlab Simulink represent that the constant frequency hysteresis control alleviates the transient bus voltage more than the sliding mode control.
