  电压调整器是维持发电机的电压为给定水平的电器。动态电压质量问题随着信息技术和自动化技术的发展越来越受到重视,动态电压调节器(DVR)是解决这一问题的主要手段。

电压调整器工作原理及种类

  一、电压调整器的工作原理

  电压调节器工作原理:由于发电机与发动机的传动比是固定的,所以发电机的转速将随发动机转速的变化而变化,汽车在运行过程中,发动机转速变化范围很大,发电机的端电压也将随发动机的转速变化而在很大范围内变化。

       发电机对用电设备供电和向蓄电池充电,都要求其电压稳定,为使电压始终保持在某一数值基本不变,就必须对发电机输出电压进行调节。电压调节器(简称AVR),是专门为配套基波、谐波复式励磁或装配有永磁发电机励磁(PGM系统)的交流无刷发电机而设计。

  二、电压调整器分类

  按调节对象可分为:

  ①直流发电机电压调整器;

  ②交流同步发电机电压调整器。

  按结构可分为:

  ①具有可动部件的电动、电磁机构的电压调整器,例如变阻式调整器、振动式调整器等;

  ②无可动部件的电子或电磁式电压调整器,例如电子离子式、磁放大器式、半导体晶闸管式电压调整器等。

  按校正作用的规律可分为:

  ①比例式(P)电压调整器,其校正规律正比于给定值和被调整值的偏差值;

  ②比例-积分-微分(PID)电压调整器,其校正规律除具有正比于给定值和被调整值的偏差值外,还具有按偏差值的积分和微分值进行调整的规律;

  ③比例-积分(PI)电压调整器,能较好地解决调整精度和稳定性两者间的矛盾。
