The voltage regulator is specially designed for matching base wave, harmonic complex excitation or ac brushless generator equipped with permanent magnet generator excitation (pgm system).
The automatic voltage regulator can adjust the output voltage of the generator automatically by controlling the excitation current of the generator ac exciter.the generator voltage regulator can meet the requirements of ordinary 60/50hz and intermediate frequency 400hz single or parallel operation of the generator
1.The ac generator voltage regulator can be divided into:
(1) contact type voltage regulator
Contact type voltage regulator has been applied earlier. This kind of regulator has slow vibration frequency, mechanical inertia and electromagnetic inertia, low voltage regulation accuracy, easy to spark contact, large radio interference, poor reliability and short life.
(2)Transistor regulator
With the development of semiconductor technology, transistor regulators are adopted.its advantages are: High switching frequency, no spark, high adjusting accuracy, light weight, small volume, long life, high reliability, small wave interference, etc.
(3)Integrated circuit regulator
In addition to the advantages of the transistor regulator, the integrated circuit regulator is also ultra-small, installed inside the generator (also known as the built-in regulator), which reduces the external connection and improves the cooling effect, and is now widely used in santana.audi and other car models on.
(4)Computer control regulator
After the system total load is measured by the electrical load detector, sends a signal to the generator's computer and the computer control 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, make the battery is enough, and can reduce the engine load, improve fuel economy.such as shanghai buick, guangzhou honda, and other car generators used this regulator.
