The classification and characteristics of 1, AC regulated power supply:

The power supply can provide a stable voltage and frequency of the said AC stabilized power supply. At present, the majority of domestic manufacturers of the work is stable AC voltage. The combination of market and some AC regulated power supply the classification characteristics.

Parameter adjustment (Xie Zhen type)

This kind of power supply voltage is LC, the basic principle of series resonant, appeared in the early stage of the magnetic saturation type regulator belongs to this category. It has the advantages of simple structure, without many of the components, high reliability voltage range is wide, anti-jamming and anti high overload capacity. The disadvantage is that large energy consumption, large noise, heavy and the cost is high.

Magnetic amplifier type electronic AC voltage regulator voltage regulator parameters based on the principle of magnetic saturation on the formation and development of 50 years in China have been popular "" (or type 614) is the principle of AC voltage stabilizer.

Self coupling (ratio) adjustment

1, mechanical pressure regulating type, namely the servo motor drives the brush moves in a self coupling transformer winding sliding surface, changing the ratio of Vo to Vi, to achieve the output voltage adjustment and stabilization. The regulator has the advantages of simple circuit, wide voltage range (130V-280V), high efficiency (≥ 95%), low price. But the weakness is the precision is low (＆#177; 8 ~ 10%) the working life is short, it is suitable for family to air conditioner power supply.

High power compensation -- purification regulator (including precision regulator)

High power compensation -- purification regulator (including precision regulator) It uses compensation link to realize the stability of the output voltage, easy to realize microcomputer control.

It has the advantage of good anti-interference performance, high voltage stabilizing accuracy (≤ ＆#177; 1%), quick response (40 ~ 60ms), simple circuit, reliable work.

It has the advantage of good anti-interference performance, high voltage stabilizing accuracy (≤ ＆#177; 1%), quick response (40 ~ 60ms), simple circuit, reliable work.

The shortcoming is: with computers, program-controlled switches and other nonlinear loads with low frequency oscillation; input current distortion, power factor is low; the output voltage phase shift of the input voltage. The anti-jamming function requirements higher unit, for the application in the city proper, computer power supply, must use 2-3 times of the total power of the regulator to use computer. The anti-jamming function requirements higher unit, for the application in the city proper, computer power supply, must use 2-3 times of the total power of the regulator to use computer. Because of high voltage, anti-interference, fast response speed, moderate price and other advantages, so a wide range of applications.
