This paper presents a simplified control model for stabilizing a load voltage using a switched reactor in parallel with a fixed capacitor of static VAR compensator. Two IGBT's are used to control the reactance of the switched reactor. A uniform pulse width modulation (UPWM) is used for controlling the two switches. The load is static and/ or dynamic, and the supply impedance is taken into account. The system parameters are selected according to the load. This compensator has a simple control circuit and structure. The load voltage and power factor are improved. Also, the supply input waveforms are found to be nearly sinusoidal. A complete modeling and numerical simulation for the proposed systems are presented. A high speed Digital Signal Processor is used for implementing proportionalintegral (PI) and fuzzy load voltage controllers. The system behavior is obtained under both transient and steady-state conditions. The steady-state waveforms are analyzed into their harmonic contents. Experimental results indicate the superiority of fuzzy logic control over the conventional proportional-integral control methods. Simulation results are reported and proved to be in good agreement with the relevant experimental results.
