What is AC regulated power supply
An electronic device that can provide a stable AC power supply or DC power supply for the load, including two categories: AC regulated power supply and DC regulated power supply.
AC regulated power supply is also called AC voltage stabilizer. With the development of electronic technology, especially after the application of electronic computer technology to various industries and scientific research fields, all kinds of electronic equipment require a stable AC power supply, and the direct power supply of the grid can no longer meet the needs. a question.
Commonly used AC regulated power supplies are:
①Ferromagnetic resonance AC voltage regulator. Composed of saturated choke coils and corresponding capacitors, it has constant voltage and voltage characteristics.
②Magnetic amplifier type AC voltage stabilizer. The magnetic amplifier and the autotransformer are connected in series, and the electronic circuit is used to change the impedance of the magnetic amplifier to stabilize the output voltage.
③Sliding AC voltage stabilizer. The output voltage is stabilized by changing the position of the sliding contact of the transformer.
④ Inductive AC voltage regulator. By changing the phase difference between the secondary and primary voltages of the transformer, the output AC voltage is stabilized.
⑤Thyristor AC voltage regulator. Thyristors are used as power adjustment components. High stability, fast response and no noise. However, it may cause interference to communication equipment and electronic equipment.
After the 1980s, three new types of AC stabilized voltage sources appeared: compensated AC voltage stabilizer. Numerically controlled and stepping AC voltage regulators. Purified AC voltage stabilizer. It has a good isolation effect and can eliminate the spike interference from the power grid.
