Basic Classification Of Voltage Regulators

1. The alternator voltage regulator can be divided into:

(1) Contact type voltage regulator

Contact-type voltage regulators were used earlier. This regulator has a slow vibration frequency of contacts, has mechanical inertia and electromagnetic inertia, has low voltage regulation accuracy, is prone to sparks, has large radio interference, poor reliability, and short life. has been eliminated.

(2) Transistor regulator

With the development of semiconductor technology, transistor regulators have been adopted. Its advantages are: the switching frequency of the triode is high, no sparks are generated, and the adjustment accuracy is high. It also has the advantages of light weight, small size, long life, high reliability, and low radio interference. It is now widely used in Dongfeng, Jiefang and various Mid-range models.

(3) Integrated circuit regulator

In addition to the advantages of transistor regulators, integrated circuit regulators also have ultra-small size and are installed inside the generator (also known as built-in regulators), reducing external wiring and improving cooling effects. They are now widely used in Santana . Audi and other car models.

(4) Computer control regulator

After the total load of the system is measured by the electrical load detector, a signal is sent to the generator computer, and then the engine computer controls the generator voltage regulator to switch on and off the magnetic field circuit in a timely manner, which can reliably ensure the normal operation of the electrical system, so as to ensure the normal operation of the electrical system. The battery is fully charged, which reduces the engine load and improves fuel economy. Such regulators are used in car generators such as Shanghai Buick and Guangzhou Honda.

2. Voltage regulators [1] can be divided into:

(1) Internal ground type regulator

The voltage regulator suitable for matching with the internal ground type alternator is called the internal ground type regulator;

(2) External ground type regulator

A voltage regulator suitable for matching with an external ground type alternator is called an external ground type regulator.

During use, for transistor regulators, it is best to use the regulator specified in the car's manual. If other models are used instead, the substitute regulator must be the same as the original regulator except that the specified parameters such as nominal voltage are the same as the original regulator. The grounding form is the same, otherwise, the generator may not work normally due to the failure of the excitation circuit. For integrated circuit regulators, they must be dedicated and cannot be replaced.
