| 摘 要： | 将三相逆变器控制的求解问题转化为数学函数的优化问题,采用遗传算法是解决数学优化的较好的方法,并能解决目前许多控制策略中THD(谐波畸变率)和开关损耗不能兼顾的问题。建立三相全桥逆变器的数学模型,编制C语言及MATLAB程序进行仿真试验,最后得出仿真实验波形并计算出THD和开关损耗。与常规控制策略输出波形比较,证明了该算法的可行性及优越性。

| Abstract: | The controlling of three-phase converter is treated as the mathematical optimizing problem. The Genetic Algorithm is applied to balance the THD (total harmonic distortion) and the switching loss. A mathematical model is established based on concrete characteristics of three-phase converter control. Simulation experiments are conducted with C language and MATLAB programmer. The THD and the switching loss are calculated according to the output waves. Compared with the routine control strategy through the theoretic analysis, the simulation results prove that this control strategy is feasible. |
