The working principle of a voltage regulator

A voltage regulator, in simple terms, is a device that can stabilize the output voltage. Voltage regulator adjustment
Composed of voltage circuit, control circuit, and servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, causing the position of the voltage regulator carbon brush to change. By automatically adjusting the coil turn ratio, the output voltage is maintained stable
With the rapid progress of society, the number of electrical devices is increasing day by day. But the aging of power transmission and distribution facilities
Due to reasons such as lagging development, poor design, and insufficient power supply, the voltage of end users is often too low, while the voltage of end users is often too high. For electrical equipment, especially high-tech and precision equipment with strict voltage requirements, it is like an indefinite bomb.
As a public power grid, the municipal power system is connected to thousands of various loads,
Some of the larger inductive, capacitive, and switching power loads not only obtain electricity from the power grid, but also have an impact on the power grid itself, deteriorating the power supply quality of the power grid or local power grid, causing distortion or frequency drift of the mains voltage waveform. In addition, unexpected natural and human accidents, such as excessive load voltage, earthquakes, lightning strikes, open circuits or short circuits in transmission and transformation systems, can endanger the normal supply of electricity, thereby affecting the normal operation of the load.
So using a voltage regulator, especially high-tech equipment with strict voltage requirements
It is essential for precision equipment.
