Why simulate?

The use of a circuit simulator is more and more necessary in teaching electrical engineering or power electronics. This technique makes it possible to obtain results when the hardware is missing. Simulation being widely used in the industry it is thus necessary to initiate our students to this technique.

  Why Pspice?

Among many simulation softwares on the market, Pspice has various advantages:

- It is based on the industrial standard Spice and thus gives access to vast libraries of models developed by manufacturers.
- Pspice is a very popular software in industry.
- It is quite easy to learn for our students.

The professional version of Pspice is far too expensive for most of us. But fortunately there is the demo version which is completely free and easily obtainable.
A demo version is always limited, of course, but here the limit is only in the number of connections which one can simulate. All the other features are available.
We have been using Pspice in electrical engineering courses for three years. For this purpose we developed a library of especially adapted parts. We thus managed to take into account all the aspects of an electromechanical system: power electronics, mechanics, regulation, with only one software. Moreover a free software!
The object of this paper is to demonstrate this whith a classic example : the speed control of a DC motor.
