Expert system based switched mode power supply design

The design of power electronic systems requires considerable expertise in exploring a wide range of complex and tedious tasks. Faster design times and a more efficient design are among the advantages that can be achieved using an expert system to assist with the task. This paper describes an expert system (XpertPSD) with extensive knowledge bases linked to a circuit simulator (SPICE) to assist the design of switched mode power supplies. It is expected that the techniques described in this paper can be applied to other power electronic systems.
