What are the types and characteristics of regulators?
The voltage stabilizer is 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.
There are large-scale and small-scale voltage regulators. Large-scale power regulators with tens to hundreds of kilowatts are the working power supply for large-scale experimental equipment; small-scale AC regulators with a few watts to several kilowatts are used for Small laboratories or household appliances provide high-quality power.
The fully automatic compensating power regulator uses a motor to drive the carbon brush to slide between the turns of the self-coupling transformer to directly adjust the output voltage or adjust the output voltage through a compensation transformer.
The AC purification regulator adopts a combination of sine wave energy distribution and filter, and adjusts the output voltage by adjusting the conduction angle of the primary loop thyristor.
The non-contact AC voltage regulator switches one or more groups of thyristors when the voltage or current crosses zero, so that the compensation windings of one or more transformers in the compensation transformer group are boosted, stepped down, and primary short-circuited. Or switch the tap from the lotus coupling transformer to adjust the output voltage.
The parametric regulator uses the saturation characteristics of the core material to highlight that the output voltage is basically stable.
The magnetically amplified AC voltage stabilizer stabilizes the output voltage by changing the magnetic resistance of the magnetically amplified transformer connected in series in the primary circuit of the autotransformer.
