| 摘 要： | 为解决逆变器中波形的优化和减少开关损耗的问题，将遗传算法运用于三相四线制中。建立了三相逆变器的数学模型，分析了各个状态变量对输出电流的影响，得出相关的计算结果。列出多目标函数的表达式，在同时考虑开关损耗和电磁干扰的情况下，利用遗传算法寻找最优序列，通过仿真实验画出最优序列下及约束条件下的波形图，并与滞环控制相比较，证明了该算法的有效性和优越性。

| Abstract: | In order to solve the problems of waveform optimization and reduce the switching loss in inverter,genetic algorithm was applied in three-phase four-wire system. Mathematical model of three-phase inverter was built,the impact of each state variable on output current ana-lyzed and the related calculation result obtained. Expressions of multiple objective functions were listed and the most optimized sequences were searched with genetic algorithm under consideration of both switching loss and EMI. Waveforms und... |
