Design Optimization of Industrial Motor Drive Power Stage Using Genetic Algorithms

A design optimization tool of motor drive power stage has been developed. Through analyzing and modeling three major blocks, including front-end harmonic filters, IGBT inverters, and EMI filters, in a industrial motor drive, optimization programs have been implemented by using Genetic Algorithm (GA) engine. The optimizer can be used as design and verification tools useful for practicing engineers. The design results obtained from the optimizer have been implemented and tested, and the experimental results have verified the models and programs.
