Methodology for computer-aided design of electrical drives

The authors deal with a modern approach to predict the behaviour of electrical drives using CAD (computer-aided design) with a dedicated methodology. The drive systems are built around several components which have their own technology with multiple time-scales; electrical machines, power semiconductors, and control circuits and the firing sequences to the different regulators. By using digital simulation as a reliable way, an original procedure has been implemented to test the different dynamics from the very beginning of the electrical and mechanical machine models to the other sub-systems with step-by-step optimizations.
