1. The alternator voltage regulator according to the principle of work can be divided into:

(1) with contacts voltage regulator

Touch point voltage regulator application earlier, this kind of controller contact vibration frequency is slow, there are mechanical inertia and electromagnetic inertia, low voltage regulation precision, contact easy to produce sparks, the radio interference, poor reliability and short service life, is now obsolete.

(2) the transistor regulator

With the development of semiconductor technology, adopted the transistor regulator.Its advantage is: the triode switch frequency is high, and does not produce sparks, high controlling accuracy, but also has a light weight, small volume, long service life, high reliability, the advantages of small wave interference, is now widely used Yu Dongfeng, liberation and various low-standard cars.

(3) integrated circuit regulator

Integrated circuit regulator, besides has the advantages of the transistor regulator has a subminiature, installed in the interior of the generator (also called built-in regulator), reducing the wiring outside, and the cooling effect is improved, is now widely used in the santana.Audi and other car models.

(4) computer control regulator

Computer control regulator is now car USES a new type of regulator, the system total load is measured by the electrical load detector, sends a signal to the generator's computer and computer controlled by the engine generator voltage regulator, circuit timely on and off the field, which can guarantee the normal work of the electrical system in a reliable way, the battery is enough, and can reduce the engine load, improve fuel economy.Such as Shanghai buick, guangzhou Honda and used the regulator on the generator.

2. The electronic controller according to the matched ac generator by iron type can be divided into:

(1) inside take iron type regulator:Is suitable for the joints with the iron type ac generator within the electronic regulator called the matched by iron type regulator;

(2) plus iron type regulatorType: suitable for joints with outside iron alternator the matched electronic regulator called plus iron type regulator.

In use process, the regulator transistor, it is best to use specified in the instructions for auto regulator, if other models in alternative, in addition to the nominal voltage regulation parameters, such as the same as the original regulator, alternative regulator must be same as the original set iron regulator form, otherwise, the generator may be due to the excitation circuit can not work normally.For integrated circuit regulator, must be dedicated and is irreplaceable.
