Matlab/GUI interface for simulation of electronic converters

Computational tool for modeling and simulation Matlab/Simulink is one of the program packages for simulation of electrical behaviour of power electronics circuits. Besides all its advantages, primarily its efficient numerical core, its shortcomings include graphically complex block schemes used in Simulink to create the simulation models. An additional drawback of this method of creating simulation models is knowledge of the basics of Matlab/Simulink software package. This paper describes an application developed in the Matlab/GUI environment that represents an interface between the user and the prepared base of simulation models of typical circuits of electronic converters. The user selects converter circuits from the base that are represented by usual electrical schemes. Element model parameters in the simulated schemes can be changed as well as conditions for progress of transient simulation. Upon completion of the simulation the simulated waveforms are shown in the same window as the electrical scheme. The user does not need to know how to work with the simulation program ; one only needs to concentrate on the analysis of operation of the simulated converter circuits.
