Small knowledge of voltage regulator

When it comes to voltage regulators, I think everyone knows something. As the name suggests, it serves to stabilize the voltage. When the voltage is high, it will drop, and when the voltage is low, it will rise again. As a high-tech product, it has a lot of professional knowledge. Today, the editor of Yutong will share with you the little knowledge about voltage stabilizers.
The original power stabilizer relied on the jump of the relay to stabilize the voltage. When the grid voltage fluctuates, the automatic correction circuit of the power regulator is activated to activate the internal relay. Forcing the output voltage to stay near the set value, this circuit has the advantage of simple circuit, but the disadvantage is that the voltage regulation accuracy is not high and every time the relay jumps and shifts, it will cause an instantaneous interruption of the power supply and cause spark interference.
The later and current regulators are generally industrial-grade regulators. Industrial-grade regulators use the principle of induction to adjust the voltage. There is no contact in the load and the linear buck-boost adjustment is performed. During the voltage adjustment, there will be no frequency deviation. The power quality of the load is the same as the input end. It is composed of industrial grade parts with high efficiency and wide safety range, which can withstand harsh temperature, humidity, vibration and dirty environment.
The voltage stabilizer is mainly composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator , By automatically adjusting the coil turns ratio, the output voltage is kept stable. The voltage regulator with larger capacity also works on the principle of voltage compensation.
