What is the Difference Between A Voltage Regulator and A Transformer?

Voltage regulator:

Voltage regulator It is a device that stabilizes the output voltage of an unstable voltage. The main components of the regulator are voltage regulating circuit, control circuit, and servo motor; When the input voltage is unstable or the load changes, its control circuit will sample, then compare, and amplify, by driving the rotation of the servo motor, the position of the regulator carbon brush changes, and then automatically adjust the number of coils, so that the work can maintain a stable output voltage.

Application of voltage regulator:
It is mainly used in industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, posts and telecommunications, hotels, scientific research and other departments of electronic computers, precision machine tools, computed tomography (CT), precision instruments, test equipment, elevator lighting, imported equipment and production lines and other places that need stable voltage power supply. The same voltage regulator is also suitable for the power supply voltage is too low or too high, the fluctuation of the low voltage distribution network end users and load changes of large electrical equipment, the main especially suitable for all the power grid waveform requirements of high voltage regulation places. High power compensation type power regulator can be connected to fire, hydraulic, small generators.

The transformer mainly uses the working principle of electromagnetic induction to change the AC voltage of the device, the main composition of the transformer is composed of primary coil, secondary coil and iron core (magnetic core). The main functions of the transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on.
According to the use can be divided into: power transformers and special transformers (electric furnace transformer, rectifier, power frequency test transformer, voltage regulator, mine transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.).

What is the difference between a voltage regulator and a transformer?
1. The role of the voltage regulator is mainly to stabilize the voltage within the required range, the voltage regulator is generally divided into two kinds, one is AC voltage regulator, one is DC voltage regulator; The difference between the voltage stabilized by the regulator and the actual output voltage value is not too big.
2. The role of the transformer is mainly to change a voltage into another needed voltage of a device, transformers are generally AC transformers, the difference between the two voltage transformers is very large, under normal circumstances several times the change. According to the number of turns, the transformer is divided into two turn transformers and three turn transformers.
