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.
