Principles of three major types of voltage regulators

The voltage stabilizing methods of voltage regulators can be divided into three categories:

TypeI: oil immersed voltage regulators;

TypeIII: Contactless voltage regulators.

Classified by phase number: three-phase voltage regulator and single-phase voltage regulator

I. Oil immersed voltage regulator:
1. Oil immersed voltage regulators are also known as intelligent voltage regulators or induction voltage regulators due to their lack of carbon brushes;
2. The overall capacity of the oil immersed voltage regulator is relatively large, and the movement adopts a brand new optimized design;
3. The stability, durability, and energy-saving performance of the oil immersed voltage regulator are superior to other products of the same level;
4. The host is contactless voltage regulation, wear free, and low loss;
5. The circuit monitoring system adopts technologies such as digital circuits and software programming to achieve input voltage sampling, high-speed operation of A/D and D/A conversion, and the entire process of output voltage Control, with the characteristics of stable operation, fast response speed, and high voltage stabilization accuracy;
6. The entire machine has a compact structure and beautiful appearance, suitable for various industries that require high voltage stability and long-term load operation.

II. Carbon brush voltage regulator
The carbon brush voltage regulator detects the output voltage through the control circuit, and then calculates the voltage difference, and then drives the servo machine to rotate to remove the position of the carbon brush head on the Pressure regulator, so as to achieve a stable output position.

III. Contactless voltage regulator

The contactless voltage regulator is currently the most advanced voltage stabilizing equipment, and the product adopts DSP microcomputer control, which combines microcomputer control with thyristor drive technology. It can achieve the characteristics of fast voltage stabilization speed and high voltage stabilization accuracy.
