摘　　要：本文探讨了他激式ＰＷＭ型开关电源闭环特性的最佳化设计问题，建立了“二次性能指标”权值ｑ与系统动态指标σｐ、ｔｓ及阻尼比ξ间的解析关系，并给出了设计与实现开关电源最好闭环传递函数的方法。The optimum design problem of the closedloop dynamic behaviors of a PWMtype switching power supply with extradrivings is studied in this paper.First of all, a few analytic relationships between the weighting factor q of the integral squared error function and the dynamic property index of the switching power supply system,which is the overcontrol quantity σp,the adjustment time ts or the dampratio ξ, are respectively established. Secondly,a method for Designing and realizing the best closed-loop transfer function is given.Lastly,a design exemplification shows that it is very valid to improve upon the voltage-stable loop dynamic behaviors by using this method .
