GA optimisation and FEM analysis of PWM inverter inductor for LCL filter

摘要

In this paper a mathematical model for design and optimisation of main inductor in a LCL filterudusing genetic algorithm is presented. The objective function for the optimisation is selected to be theudefficiency of the inductor. Two different optimization search have been performed using the same objectiveudfunction, but with different number of optimisation parameters. From these optimisations two differentudinductor solutions were realized with lower inductor losses and decreased temperature rise. Finite ElementudMethod is used for further analysis of the two optimal designed solutions.
