摘 要 :汽车用交流发电机的输出电压大多是由发电机内置的调节器控制的.调节器的作用是检测外部电压信号,控制交流发电机的输出电压在恒定的范围内.调节器检测外部电压信号的方法,即电压取样方法归纳起来有3种方式:发电机电压取样法、蓄电池取样法、综合电压取样法.

关 键 词 :交流发电机 输出电压 电压取样法 车型应用

Abstract: Automotive alternator output voltage generated by the generator is mostly controlled by a built-in regulator. The role of the regulator is to detect the external voltage signal within the control of the alternator output voltage at a constant range. Methods to detect the external voltage regulator signal, that summed up the voltage sampling three ways: generator voltage sampling method, sampling battery, integrated voltage sampling method. Among them, the generator voltage sampling method there are two methods: DL excitation voltage diode rectifier diode DM sampling and voltage sampling method, various methods he advantages and disadvantages, there are used on a variety of models. Here, the regulator will introduce a generator voltage of my pany's sampling method for everyone, for reference.


Keywords: alternator output voltage of the voltage sampling

一、工作原理及优、缺点分析

三、结论

综上所述,调节器采用此双电压取样电路后,互相取长补短,在电路设计及制作上几乎不增加成本,而且,整车线路不需要做太大的改变,电路连接相对比较简单,经过多年实际应用,工作可靠性高,虽然没有克服蓄电池电压取样法因为取样电路与蓄电池正极B常连接,消耗无为的缺点,但是,各方面综合考虑,实际应用价值极高,因此,建议同行广泛采用.
