Working Principle:
The working principle of a three-phase AC voltage stabilizer mainly includes the following steps:
Input Voltage Detection: The voltage stabilizer first detects the input three-phase AC voltage.
Voltage Comparison: The detected input voltage is compared with the preset target voltage.
Adjusting Circuit: Based on the result of the voltage comparison, the voltage stabilizer adjusts the output voltage through the adjusting circuit. Common adjustment methods include:
Voltage-Regulating Transformer: Adjusting the voltage by changing the turns ratio of the transformer.
Servo Motor Drive: Driving the carbon brush to move on the sliding rheostat by the servo motor to change the resistance value and thus adjust the voltage.
Electronic Control: Using electronic components (such as thyristors, IGBTs, etc.) to adjust the voltage.
