PSpice simulation of power electronic and motion control systems

This paper presents an hierarchical approach to the modelling and simulation of power electronic and motion control systems. Several ways to simplify the models and to speed-up simulation are proposed. A new method of creating simple, reliable and fast models of power electronic switches is presented. A concept of the ideal modulated transformer and gyrator as the fundamental elements of the power converter model is discussed. Several models of voltage source inverters are compared. A modular approach to the modelling of electrical machines and three-phase transformers is presented. Some examples of numerous models created by the author are shown. All examples have been prepared using PSpice A/D and Schematics, version 6.3, but the general methods and hints can also be helpful for users of other circuit-oriented simulation packages.
