Teaching the PWM AC Voltage Controller Using Matlab Graphical User Interface

This paper presents an adequate approach for teaching the sinusoidal pulse width modulation (SPWM) in AC voltage control regulators. In this paper the graphical user interface (GUI) functions, which constitute one of the important pillars of Matlab software, are developed to an easy-to-use educational software tool. Single-Phase AC voltage controller is mathematically modeled and then simulated using basic Matlab commands. GUI is implemented to construct an active link with these models. So that, instructors can demonstrate the change in SPWM system response due to parameter variation. An example, using the GUI, is provided to demonstrate the usefulness of the developed software
