·AC Regulated Power Supply

AC power supply also known as AC voltage stabilizer. With the development of electronic technology, especially computer technology to various industries, scientific research fields, the variety of electronic devices require a stable AC power supply, power supply can not meet the direct needs of the emergence of AC power supply solution this problem.

Commonly used in AC power supply are: ① ferro-resonant AC voltage stabilizer. By the saturated choke with the corresponding capacitor, has a constant voltage-V characteristics. ② Magnetic Amplifier AC regulator. The magnetic amplifier and auto-transformers in series, using electronic circuits to change the impedance of magnetic amplifier to stabilize the output voltage. ③ Slide AC regulator. Transformer by changing the position of sliding contact stable output voltage. ④ Inductive AC voltage stabilizer. Times by changing the transformer primary voltage of phase, so that the output AC voltage stability. ⑤ Thyristor AC regulator. With the thyristor as power adjustment component, high stability, fast response and no noise, but communications equipment and electronic equipment disruptive.

The 20th century, 80 years later, appeared three kinds of new AC Power Supply: AC power supply compensation, CNC-type, and Stepper AC power supply, clean AC power supply. With good isolation effect, to eliminate interference from the power grid peak.
