摘要

针对SWISS整流器的性能问题，采用基于NSGAII算法的多目标优化方法。以离散的直流电感、IGBT、Diode以及输出电容参数建立的元器件数据库为约束条件，以效率、功率密度以及输出纹波模型为目标函数，通过NSGAII算法进行优化，并给出了帕累托最优解集和帕累托最优前沿，根据目标的优先级合理选择方案，从而选择相应器件。最后，通过仿真实验表明方案的可行性，优化后效率为96.01%，功率密度为12.95kW/dm3，输出纹波为0.068。

Abstract

Aiming at the performance problem of SWISSrectifier

a multiobjective optimization method based on NonDominated Sortingin Genetic AlgorithmsII (NSGAII) is adopted. With discrete DC inductor

IGBT

Diode and output capacitor database as constraints

and efficiency

powerdensity and output ripple model as objective functions

the optimization iscarried out by NSGAII algorithm

using the pareto optimal solution and paretooptimal front of the algorithm. We select the appropriate device according tothe priority of the target. Finally

the simulation results show that thescheme is feasible

the optimized efficiency is 96.01%

the power density is 12.95kW/dm3

and the output ripple is 0.068.
