AC voltage stabilizer, also known as AC Voltage Regulatorss. With the de velopment of electronic technology, especially computer technology applied to industrial, scientific field, a variety of electronic devices require a stable AC

power grid directly to the power supply can not meet the need, the emergence of exchange exchange Voltage Regulators solves this problem. Exchange exchange Voltage Regulators: â'  The ferromagnetic resonance exchange Voltage Regulators. Saturated

choke and capacitor, with a constant voltage V characteristics. â'¡ magnetic amplifier type AC Voltage Regulatorss. The magnetic amplifier and auto Power Transformer series, the use of the electronic circuit to change the impedance of the

magnetic amplifier to stabilize the output voltage. â'¢ Slide the AC Voltage Regulatorss. By changing the Power Transformer sliding contact position and stable output v oltage. â'£ induction type AC Voltage Regulatorss. By changing the phase

of the Power Transformer primary voltage, the output AC voltage stability. â'¤ thyristor AC Voltage Regulators. Thyristors for power adjustment component. High stability, fast response and no noise. Interfere with communications equipment and

electronic equipment. 1980s, three new exchange exchange Voltage Regulators: Compensation AC voltage stabilizer. NC and step-by-step exchange Voltage Regulators. Purification AC Voltage Regulatorss. With good isolation effect, to eliminate the

peak interference from the power grid.

AC and DC voltage Voltage Regulators, also known as AC and DC voltage Voltage Regulators. The supply voltage is AC voltage when the voltage of the AC supply voltage or output load resistance, the direct output voltage of the AC voltage stabilizer

can remain stable. The parameters of the AC Voltage Regulatorss voltage stability, t he ripple coefficient and speed of response. The former said that the change on the output voltage of the input voltage. The ripple factor is the size

of the AC component, the output voltage under the rated working; the latter said that the input voltage or load changes dramatically when the voltage back to the normal time required. DC power supply is divided into two types of

continuous conduction type and switching type. Single or three phase AC voltage change to the appropriate value of the former by the working frequency Power Transformer, then rectified, filtered DC power supply, unstable, stable

voltage (or current) and then by the Voltage Regulators circuit. Power lines, ripple, mutual interference is small, but bulky, supplies, efficiency is low (often less than 40% ~ 60%). The latter to change the element (or switch) off time than to

regulate the output voltage, so as to achieve the Voltage Regulators. Such power consu mption is small, the efficiency up to about 85%, but the drawback is that the ripple is large, and interfere with each other. Therefore, the rapid

development since the 1980s. From the work can be divided into: â'  The controllable rectifier. Change the thyristor conduction time to adjust the output voltage. â'¡ chopper. The input is unstable DC voltage, to change the switch

circuit off than unidirectional pulsating DC stable DC voltage is then filtered. â'¢ converter type. Unstable DC voltage by the inverter and transform into a high-frequency alternating current via a Power Transformer, rectifier, filter, sampling

from the proceeds of the new DC output voltage feedback control of the inverter operating frequency to achieve the purpose of stabilizing output DC voltage.
In mobile phone repair, in order to facilitate the testing, the need to prepare for an AC Voltage Regulatorss output voltage adjustable output voltage of 1-15 V, 1-2 c urrent security, with short-circuit protection circuit and adjust the

current limit, with mechanical The two-type header and digital display, used to observe the current changes in the mobile phone work

[Use]:
Exchange exchange Voltage Regulators [1] are widely used in computers and peripheral devices, Voltage Regulatorss and protection of medical electronic equipment, communication and broadcasting equipment, industrial electronic equipment,

automatic production line of modern high-tech products.

AC and DC voltage Voltage Regulatorss are widely used in national defense, scientific research, universities, laboratories, industrial and mining enterprises, electrolysis, electroplating, charging devices such as DC power supply.
AC voltage stabilizer - the history of
U.S. scientists Ronaldo (GHRoyer) in 1955 developed the first successful use of the saturation of the core to the self-oscillating transistor DC-DC convert er. Since then, the excellence of the various forms of this technology [2] have

been developed and emerged, replacing the early adopters of the short life, poor reliability, and low conversion efficiency of rotation and mechanical oscillator shows the converter device. Transistor DC-DC converter power

transistors in the switch state, so the number of exchange Voltage Regulators output group made, the polarity variable, high efficiency, small size, light weight, and thus was used in aerospace and military electronics equipment. That

microelectronics equipment and technology is very backward, can not produce high pressure, high switching speed and power transistors, DC-DC converter of this period only a low voltage input, and the conversion rate can not

too high.
1960s, due to the rapid development of microelectronics technology, the high reverse voltage of the transistor from the DC-DC converter can directly mains rectified and filtered input, no longer need to power frequency step-down

Power Transformer, which greatly expanded the scope of its application, and on this basis, the birth of the power frequency step-down Power Transformer, switching power supply. Eliminating the need for frequency Power Transformer, but also greatly

reduce the size and weight of the switch AC voltage stabilizer, switch AC voltage stabilizer was truly a high efficiency, small size, light weight.
After the 1970s, this technology, high frequency, high reverse voltage power transistors, high-frequency capacitance, switching diodes, switching Power Transformer cores and other components developed and produced no work-

frequency Power Transformer switching exchange stability The voltage multiplier has been rapid development, and is widely used in other fields of computer, communications, aerospace, color TV, so no work to become the leader of a

variety of power freque ncy AC voltage stabilizer Power Transformer switching.
