Design and Realization of Virtual Experimental Platform of Power Electronics Technology Based on MATLAB GUI

The course of power electronics technology has the characteristics of strong practicability,equal importance on theory and practice.In this paper,a virtual experimental platform for power electronics technology is established in order to get better teaching effect.The platform based on MATLAB GUIDE(graphical user interface development environment)has three interactive interface,including login interface,circuit select interface and simulation interface.Through the above human-machine interaction interface,it can realize circuit simulation and parameter setting,display the results using graphics.Students not only can analyze the influence of parameter variation,but also create device library and circuit through the platform.
