| Summary: | Aiming at the performance problem of SWISS rectifier, a multiobjective optimization method based on NonDominated Sorting in Genetic AlgorithmsII (NSGAII) is adopted. With discrete DC inductor, IGBT, Diode and output capacitor database as constraints, and efficiency, power density and output ripple model as objective functions, the optimization is carried out by NSGAII algorithm, using the pareto optimal solution and pareto optimal front of the algorithm. We select the appropriate device according to the priority of the target. Finally, the simulation results show that the scheme is feasible, the optimized efficiency is 96.01%, the power density is 12.95kW/dm3, and the output ripple is 0.068. |
