摘　　要：整流滤波电路用途广泛但其优化设计不易得到全局最优解。对单相桥式不控整流电路的LC滤波器进行深分析,得到输出平均电压、浪涌电流、振荡电压、谐波衰减比和体积等的表达式f(L,C,R),并在Matlab环境下用四维数据场展现其全局的值域分布,按需用不同交集来表征所须兼顾的多个设计目标,逐步导入约束条件来进行优化。实验结果表明,在滤波器外特性基本相同的前提下,基于数据场可视化算法的优化设计达到了体积缩小1/4的效果。The rectifier filter circuit is widely applied. However, it encounters the difficulty of a global solution. Single-phase diode bridge rectifiers with LC filters were investigated, the expressions f（L,C,R） of average DC output voltage, inrush current, inrush voltage, transfer function and volume were obtained respectively. Moreover, according to the four dimensional data field, the global distributions of range was displayed using Matlab. By finding out the overlap region of the various design targets, the optimal design was made gradually according to corresponding restriction conditions. The experimental results show that, the analysis and design optimization of LC filters based on the data field four-dimensional visual algorithm can effectively reduce the volume to 1/4 under the similar external characteristics conditions of the filter.
