A systematic computer-aided design methodology is needed to get an optimized control loop design for power electronic dc-dc converters. This paper will present the development of a frequency- and time-domain simulation for an efficient loop design. Furthermore the practical control loop design of a flyback converter will be presented and verified with a vector network analyzer. It will be shown that the implemented models are accurate enough to get a suitable controller design. In further work, the authors upgraded the model library to other basic switched-mode power supply (SMPS) topologies. In this way, it is possible to use the simulation tool for a wide variety of power converter designs.
