> A static converter is an electrical circuit which can control the transfer of energy between a generator and a receiver. The efficiency of a converter should be excellent. The components constituting a converter are:


The design of power converter consumes time with a significant cost. Performance is generally determined after testing converters at nominal operating points. Thus, simulation can substantially reduce development cost.

The development of specific software dedicated to simulation of power electronic systems (PSIM, SABER, PSCAD, "SimPowerSystems" toolbox of Simulink…) allows simulating fast and accurately the converter behavior. Unfortunately, the designers of converters don't always have such available software. In many cases, they have to simulate power electronics devices for occasional need. So they don't want to buy the SimPowerSystems toolbox in addition to Matlab and Simulink. The purpose of this chapter is to present the ability to simulate power converters using only Simulink. Simulink is a graphical extension to MATLAB for representing mathematical functions and systems in the form of block diagram, and simulate the operation of these systems.

Traditionally two approaches are used to simulate power electronic systems:

In this chapter, we propose a method for simulating static converters with Simulink based on the variable topology approach where switching conditions of semiconductor are realized by switching functions.
