What are the main types of power supply?
Category: divided into the following four categories:
AC power supply
DC power supply
Inverter power supply
Switching power supply
AC power supply
Also known as AC voltage regulator. With the development of electronic technology, especially the application of electronic computer technology to various industrial and scientific fields, all kinds of electronic equipment require stable AC power supply, power supply directly can not meet the needs of the exchange of power supply to solve this A question.
Commonly used AC power supply are:
??Magnetic Resonance Resonant AC Voltage Regulator. By the saturated choke and the corresponding capacitor composition, with constant voltage volt-ampere characteristics.
??② magnetic amplifier type AC voltage regulator. The magnetic amplifier and autotransformer in series, the use of electronic circuits to change the impedance of the magnetic amplifier to stabilize the output voltage.
??③ sliding AC voltage regulator. The output voltage is stabilized by changing the position of the transformer sliding contact.
??④ Inductive AC voltage regulator. By changing the transformer secondary, the primary voltage of the phase difference, so that the output AC voltage stability.
??⑤ thyristor AC voltage regulator. Use thyristor as power adjustment element. High stability, fast response and no noise. But cause interference to communication equipment and electronic equipment. After the 1980s, there were three new AC regulated power supplies: compensated AC voltage regulators. NC and stepped AC voltage regulators. Purified AC voltage regulator. Has a good isolation, can eliminate the spikes from the power grid interference.
