Low cost program for simulation of power electronic converters and systems

The authors state that the use of simulations tools is very important, especially in order to get an increased understanding of a converter´s or system´s behaviour. The authors present a simulation example (controlled thyristor DC-motor drive) which requires a powerful simulation tool. The authors show that a low cost program sold on a noncommercial basis can be used for these simulations. The authors focus on a program which offers ideal component models together with possibilities of inclusion of more advanced models. The program used is KREAN which is a special purpose program for simulation of power electronic converters and systems. The program is shown to work very well on the selected example. The presented results corresponds to what should be expected from a idealized circuit. The results are presented in order to illustrate the capabilities of the program and the power of simulations for illustration of circuit behaviour
