摘要
由于高频变压器通常工作在复杂激励条件下,采用传统AP法设计时往往无法同时平衡兼顾多个目标之间的关系,文中选取了磁芯损耗和绕组损耗计算模型和磁芯面积法公式作为目标函数,以变压器效率为约束条件,以减小损耗提高效率为目标,采用改进仿推特算法进行高频变压器多目标优化设计。通过采用自适应交叉变异概率调整种群多样性、加入Pareto支配关系以提高种群的优越性,优化了算法对于Pareto解集的寻优能力,改进了MOTO算法,为求解带约束多目标问题提供支持。引入了熵权法(EWM)对算法优化结果进行决策支持,便于决策者选择最佳折中解,得到一组高频变压器优化设计方案。最后,通过实验验证了该方案的合理性和有效性。
The traditional AP calculation method is difficult to balance the relationship of multiple goals at the same time due to the high frequency transformer usually works under complex excitation conditions.In order to solve this problem,the core loss,winding loss calculation model and core volume are selected as the objective function,with the transformer efficiency as the constraint conditions,and reduction of loss and improvement of efficiency as the objective,the improved MOTO algorithm is adopted to conduct multi-objective optimization design for high-frequency transformers.By adopting adaptive crossover and mutation probability to adjust the diversity of the population and adding the Pareto dominance relationship to improve the superiority of the population,the optimization ability of the algorithm to the Pareto solution set is optimized,and the MOTO algorithm is improved to provide support for solving multi-objective problems with constraints.The entropy weight method(EWM)is introduced to support the decision-making of the algorithm optimization results,which is convenient for decision-makers to choose the best compromise solution and obtain a set of high-frequency transformer optimization design schemes.Finally,experiments verify the rationality and effectiveness of the proposed scheme.
