This paper deals with the automatic design of static converters
and electrical machines. Facing the multitude of such devices
(converters–machines), the choice of the appropriate converter or machine
is a delicate problem. A high level of expertise is required to
determine the best structure for the considered application.
This choice could be rapidly made if one had a system which incorporates a great
knowledge of converters, machines and control methods.
Firstly, the authors review the realized studies, then they propose
this methodology for a concrete case in order to optimize an
inverter–motor of a railway traction chain. Constraints are described
in terms of input and output performances (losses, current, ...).
These data are analyzed by using design rules and methods which allow the
decrease of the manufacture cost of the inverter–motor. Rules and methods are
implemented on a workstation by means of an “expert system shell” Smeci.
The article proposes several tracks which involve organization,
methodology, confirmation and implementation of a tool supporting a method.
This process of implementation is the most efficient to fit
into a constant process of improvement which is supported by the return
on experience and by the evolution of the state of the art.
