A novel approach to the design and implementation of a power electronics simulation software package

The novel approach is to interface Matlab and Simulink with a graphical user interface (GUI) developed in Visual C++. Object oriented programming is a new way of approaching the job of programming. Object oriented programming was used to create a separate class for each of the items and devices to be handled on the screen. This power electronics software can be used for designing, analyzing and simulating power electronics circuits using a modified nodal formulation. The graphical user interface has a screen to draw the circuit with drag and drop features for the power electronic network components. The simulation is performed by external software, namely, Matlab/Simulink. The modified nodal formulation is used on the backward Euler formula and results in an equation which governs the circuit simulation. The entire circuit connection information is passed on to the background simulation program in the form of a precisely formatted matrix.
