Pre-sizing optimization of an inverter and the passive components

This paper deals with an optimization approach of a three-phases inverter associated to a bus capacitor filter and a heatsink. This approach considers multi-technology components and a power semiconductors generic modelling. The optimized choice is performed with a Genetic Algorithm (GA) with the help of components databases for the semiconductors, capacitors and heatsinks. The aim is to minimize the overall volume by respecting electro-thermal constraints. Two optimizations are computed to analyze the switching frequency impact into the final result, the heatsink and bus capacitors volumes.
