一种串联混合动力车用无刷直流发电机双闭环励磁调节器的研制

A Sort of Double Closed-Loop Excitation Regulator for Brushless DC Generator used in Series HEV

利用TL494构成了电压调节与电流调节双闭环励磁调节器,该系统通过两个闭环共用一个PWM实时处理的方法,实现了对励磁电流快速调节迅速稳定发电机端电压的功能。实验表明,调节效果好、抗干扰能力强,动态与稳态性能均满足系统要求。

A sort of double closed-loop excitation regulator bath with voltage and current regulation loops,which is composed of TLA94,is developed. The system realizes that the excitation current can be regulated rapidly and the generator＇ s voltage be timely stabilized by the method with which the double closed loops share one PWM. It is testified by the experiments that the dynamic and static capability of this control system can meet the demand of system.
