Abstract :
Dynamic capacitive VARs are becoming more important in the modern power system. This paper gives an examination of the behavior of a dynamic capacitor based on buck and boost cells. The principle of operation and the characteristics are explained. The basic principle is extended to the series connection of cells to reach higher voltages. A simulation case is provided to demonstrate the effectiveness of the concept. Design issues and principle of control are briefly discussed.
