| Abstract | ||||
| This paper introduces a variable capacitive reactance for compensation using a series controlled capacitor for load voltage stabilization. Employing capacitors is the simplest method of reducing the effective impedance the line. The proposed system operates for load voltage stabilizing with static or dynamic load. This system improves input power factor and reduces the input line current harmonic. The proposed system is used also for mitigation of voltage sag. Simulation and experimental results are obtained for open and closed loop voltage control system. The integral proportional (PI) controller is used to control the load voltage by controlling the capacitor effect. The effectiveness of the proposed method is verified through simulation and experimental results. | ||||
