由于电压调节器是控制交流发电机输出电压大小的重要装置，又因装载机工作性质和环境的特殊性，其性能直接影响装载机上用电设备的安全性和蓄电池的使用寿命。传统的振动式调节器不能满足发电机电压变化的要求，因而有必要设计一种能防过热、过载，可短路保护且功耗低的大功率
Because the voltage regulator is an important device to control the output voltage of the alternator, the performance of the loader directly affects the safety of the electrical equipment on the loader and the service life of the battery because of the working nature of the loader and the particularity of the environment. The traditional vibration regulator can not meet the requirements of the generator voltage changes, it is necessary to design a to prevent overheating, overload, short circuit protection and low power consumption of high power
