The voltage regulator (referred to as AVR) is designed for the exchange -free generator with a brushless generator with an analogy -inductive inspirational (PGM system) of supporting base waves, harmonic duplex inspirational or assembly.

The voltage regulator controls the automatic adjustment of the output voltage of the generator through the control of the incentive current of the generator to the excitation current of the generator. The charger voltage regulator can meet the use of ordinary 60/50Hz and medium frequency 400Hz single -machine or parallel -running generators.

1. AC power supply voltage regulator can be divided into:

(1) contact voltage regulator

contact voltage regulator is used earlier. This regulator contact frequency is slow, there is mechanical inertia and electromagnetic inertia, the voltage adjustment accuracy is low. Short, it has been eliminated.

(2) Crystal Titter Tuner

With the development of semiconductor technology, the transistor regulator is adopted. Its advantages are: the switching frequency of the triode is high, and does not produce sparks, the accuracy is high, and it has the advantages of light weight, small volume, long life, high reliability, and small radio interference. Low -middle models.

(3) Integrated circuit regulator

In addition to the advantages of a transistor regulator, the integrated circuit regulator also has super small large -scale and installed in the internal (also known as the interior regulator) of the generator, which reduces the outer wiring and improves the cooling effect. Now it is widely widespread Apply to Santana. Audi such as Audi and other cars.

(4) Computer control regulator

After the total load of the electrical load detector measurement system, send a signal to the generator computer, and then the engine computer controls the electric machine voltage regulator. Work makes the battery sufficient charging, which can reduce the engine load and increase the fuel economy. Such as Shanghai Bike and Guangzhou Honda and other cars using this regulator.

2. The voltage regulator can be divided into:

(1) Iron type regulator

The voltage regulator suitable for the matching generator with an interior AC generator is called an inner iron type regulator;

(2) outer iron -type regulator

The voltage regulator suitable for the matching generator with an iron -type AC generator is called an external iron regulator.

In the process of using, for the transistor regulator, it is best to use the specified regulator specified in the car instructions. If other models are used for replacement, except for the same parameters such as the nominal voltage as the original regulator, the substitution regulator must be as the original as the original as the original. The formation of the regulator is the same. Otherwise, the generator may not work properly due to the incompatibility of the inspiration circuit. For integrated circuit regulator, it must be dedicated and cannot be replaced.
