Two types of high voltage auto load booster

step voltage regulators applied in the utility’s distribution systems are generally medium-voltage mechanical automatic voltage regulators (AVR). It should be noted that there are two distinct types of high voltage auto load booster: Medium-voltage (mechanical) and the Low-voltage regulators (mechanical or electronic). The difference in their operation and design clearly demonstrate that their applications are not the same. The latter is intended to protect end-user devices from overvoltage and undervoltage conditions.

The purpose of a automatic voltage booster

The purpose of a automatic voltage booster is to maintain the output voltage of a generator at a desired value. As load on an AC generator changes, the voltage will also tend to change. The reasons for this change in voltage is the change in the voltage drop internally across the armature winding caused by a change in load current and the changes in power factor.Because of changes in voltage, due to these factors, AC generators require some auxiliary means of regulating output voltage.Shown here is the electrical symbol used for a voltage regulator. A step voltage regulators is an electronic device connected to the output of a power supply to maintain the output voltage at its constant rated value. This is typically accomplished through the use of resistors.

The working principle of auto load booster

(1) contact type auto load booster
Contact voltage regulator application earlier, this regulator contact vibration frequency is slow, there is mechanical inertia and electromagnetic inertia, low voltage regulation accuracy, contact prone to sparks, radio interference, poor reliability, short life, now Has been eliminated.
(2) transistor regulator
With the development of semiconductor technology, the advantages of transistor regulator is: transistor switching frequency is high, and does not produce sparks, high precision, but also has a light weight, small size, long life, high reliability, radio interference, etc. Advantages, is widely used in Dongfeng, the liberation and a variety of middle and low models. 
(3) integrated circuit auto voltage stabilizer
Integrated circuit regulator in addition to the advantages of transistor regulator, but also has a small, installed in the generator inside (also known as built-in regulator), reducing the external wiring, and cooling effect has been improved, is widely used in Santana The Audi and other car models.

Automatic voltage booster

An instantly acting automatic voltage booster employing autotransformers each having a secondary winding connecting between power supply lines and a load in a three phase system for supplying power continuously to the load. Primary windings are maintained in short circuited condition by contacts of a relay actuated when voltage supplied via the supply lines remains above a predetermined minimum magnitude. The relay contacts open to energize the primary windings and induce voltage in the secondary windings when the supplied voltage falls to or below the predetermined magnitude for maintaining voltage supplied to the load above the predetermined magnitude. A switch is provided to short circuit the secondary windings and open circuit the primary windings in the event of equipment failure.
