With the recent progresses in modeling environments, the study and the simulation of electronic components that constitute electric traction have become increasingly simple and intuitive. This working approach has been introduced over the years in the field of railway traction where the management of high power levels and the need for a much greater reliability than small applications are involved. This type of study therefore allows on the one hand to reduce the costs of software development related to the expensive, in terms of time and costs, field tests. On the other hand it permits to study the system in a more detailed way in order to intervene more precisely both in implementation and maintenance.
