Introduction: a variety of electronic devices in daily life more and more, but the previous ordinary power supply can not guarantee stable AC power, unstable AC power can not meet the needs of electronic devices, therefore, AC regulated power supply randomly appeared and widely used, then, what is AC regulated power supply? What are the types and uses of AC regulated power supply? I believe that we are not very understanding of these, today I will introduce you to the relevant knowledge of AC regulated power supply, I hope you learn by heart!
What is an AC regulated power supply?
AC regulated power supply means that the use of power electronic equipment to provide a stable AC power supply of an electronic device, this device to make up for the lack of ordinary power supply devices, especially when electronic computers and other electronic equipment is widely used after the application of AC regulated power supply seems essential.
AC regulated power supply classification
First of all, AC regulated power supply can be divided into two categories: non-contact AC voltage regulator and AC voltage regulator with contact, and secondly, in these two categories, can be divided into a variety of different sub-categories.
Non-contact AC voltage regulator
1, ferromagnetic write resonant AC voltage regulator, this device is a combination of saturated choke and capacitor to produce a regulated AC a device, it has the advantage of a simple structure, easy to manufacture, reliable, widely used, the shortcomings are the degree of stability needs to be improved, the distortion of waveforms is larger. The disadvantage is that the degree of stability needs to be improved and the waveform distortion is larger. The later development of the AC voltage regulator, although the structure of the form of improvement, but also the use of the principle of this device is made.
2, inductive AC voltage regulator, this regulator is by changing the phase difference between the transformer secondary voltage and the primary voltage to achieve the purpose of stabilizing the AC voltage, its advantage is the output of a wide range of voltage regulator, waveform, power, the disadvantage of low efficiency, power consumption, so the use of a certain limit.
3, magnetic amplifier AC voltage regulator, this device has a closed-loop system of feedback control, through the electronic circuit to change the impedance of the magnetic amplifier to provide the regulated current, therefore, it is highly stable, good waveforms, but due to the inertia of the magnetic amplifier is larger, it requires a longer recovery time, interference resistance is also relatively poor.
4, thyristor AC voltage regulator, this device is the use of thyristor regulation as a power adjustment tool so as to achieve the regulated current, the advantages of good stability, reflective, does not produce noise, the disadvantage is the use of this regulated electronic equipment has a strong interference.
Touch AC voltage regulator
This is mainly sliding AC voltage regulator, this device through the transformer sliding contact position change to make the output voltage to reach a stable state, it is high efficiency, voltage waveform is good, but the stability of the lower, the need for a longer recovery time.
Application of AC regulated power supply
The application of AC regulated power supply is very wide in our life, a large number of electronic equipment makes the AC regulated power supply more and more in demand, especially in the industrial automation industry, a variety of large-scale equipment needs to be in a regulated environment in order to work properly, CNC machine tools, complete sets of equipment, Medical, broadcasting and television, hotels, etc. all need the application of AC regulated power supply, especially connected to the computer equipment, AC regulated power supply must be indispensable.
AC regulated power supply knowledge on the introduction of the end, we are not on the AC regulated power supply has a better understanding of it?
