On line simulation models of electric drives

Abstract

The paper presents an online simulation model of a dc drive supplied by a single phase full wave thyristor controlled rectifier and by a single phase cycloconverter. The model was created in Matlab to shorten the simulation running time. It is intended for real-time and rapid prototyping of dc power electronics and electrical drives. The first simulated hardware consists of a two quadrant dc controlled rectifier while the second consists of a four quadrant operation. The online simulation was compared to a conventional simulation in Simulink using Simpowersystem Blockset.
