Modelling and Simulation of Switching Mode DC/DC Converters

Modeling and simulation of switching mode DC/DC converters can be done on several ways, depending on the desired goal of modeling, complexity of converter model, availability of software tools, simulation time consumption etc. There are three basic approaches to the problem. Circuit oriented modeling (static modeling) enables simulation of converter's behaviour by means of standard or dedicated electrical circuit simulators. Dynamic modeling of power converters enables analysis of converter's dynamic behaviour for design and implementation of converter control. Dynamic modeling can be divided into circuit averaging approach and state-space approach. Each approach has its own advantages and drawbacks. The aim of the paper is to compare circuit oriented modeling and circuit averaging dynamic modeling of switching mode DC/DC converters on several bases (model complexity, accuracy of the results, simulation time etc.)
