Abstract

One of the most important concerns in manufacturing industries and utilities over the utilization of voltage controlled voltage source inverters (VCVSIs) is to generate and maintain a steady sinusoidal output voltage to the critical load which has been the focus of considerable research in recent years. VCVSIs output voltage fluctuation may be caused by abrupt or periodic changes of the load current that are significant. The purpose of this paper is to keep the amplitude of the output voltage wave form at the reference level under these conditions. The proposed method presents a fast voltage variation detection technique using phase space mathematical method to improve voltage fluctuation. A controller that takes advantage of this detection method is applied to a full bridge inverter to keep the voltage level at the desired point. To investigate the efficiency and accuracy of the proposed controller, a system is modeled using Matlab/Simulink and the results is compared with open-loop and RMS controllers. The simulation results approve the capability of the proposed controller to provide a sinusoidal output voltage and mitigate voltage fluctuation to a considerable level by using phase space method.
