There are many types of regulated power sources, whose function is to filter the mains electricity; The voltage required to stabilize various electrical appliances and circuits is called a regulated power supply. The definition of a regulated power supply is an electronic device that can provide stable AC or DC power to a load, including two categories: AC regulated power supply and DC regulated power supply.

AC voltage stabilizer, also known as AC voltage stabilizer. With the development of electronic technology, especially the application of electronic computer technology in various industrial and scientific research fields, various electronic devices require stable AC power supply, and direct power supply from the power grid can no longer meet the needs. The emergence of AC stabilized power supply has solved this problem.

Commonly used AC regulated power sources include:
①Ferromagnetic resonant AC voltage regulator. Composed of a saturatedchoke and corresponding capacitors, it has constant voltage volt amperecharacteristics.
②Magnetic amplifier type AC voltage stabilizer. Connect the magneticamplifier and autotransformer in series, and use electronic circuits to changethe impedance of the magnetic amplifier to stabilize the output voltage.
③Sliding AC voltage regulator. Stabilize the output voltage by changing thesliding contact position of the transformer.
④Inductive AC voltage regulator. By changing the phase difference betweenthe secondary and primary voltage of the transformer, the output AC voltage isstabilized.
⑤Thyristor AC voltage regulator. Use thyristors as power adjustmentcomponents. High stability, fast response, and no noise. But it causesinterference to communication and electronic equipment. After the 1980s,three new types of AC voltage stabilizers emerged: compensated AC voltagestabilizers. CNC and stepper AC voltage regulators. Purified AC voltageregulator. It has good isolation effect and can eliminate peak interference fromthe power grid.

The purpose of AC regulated power supply:

AC stabilized power supply is widely used for the stabilization and protection of modern high-tech products such as computers and their peripheral devices, medical electronic instruments, communication and broadcasting equipment,
industrial electronic equipment, and automatic production lines.
