What Are The Parameters And Quality Indicators Of Wide Range Voltage Stabilizer And Ac Regulated Power Supply?

An electronic device that can provide a stable AC power supply to the load, also known as Wide Range Voltage Stabilizer. For the parameters and quality indicators of AC stabilized power supply, please refer to DC stabilized power supply. Various electronic devices require a relatively stable AC power supply, especially when computer technology is applied to various fields, the method of directly supplying power from the AC power grid without taking any measures can no longer meet the needs.

With the development of power supply technology, the following three new types of AC stabilized power supplies appeared in the 1980s. ① Wide range stabilizer: also known as partial adjustment stabilizer. The additional voltage of the compensation transformer is connected in series between the power supply and the load. With the input voltage, the size or polarity of the additional voltage is changed by using an intermittent AC switch (contactor or thyristor) or a continuous servo motor, and the higher (or insufficient) part of the input voltage is subtracted (or added) to achieve the purpose of voltage stabilization. The capacity of the compensation transformer is only about 1/7 of the output power, with the advantages of simple structure and low cost, but the stability is not high. ② Wide range voltage regulator and stepping voltage regulator: The control circuit is composed of logic elements or microprocessors, and the primary turns of the transformer are converted according to the input voltage to stabilize the output voltage. ③ Wide range voltage regulator: It has good isolation and can eliminate spike interference from the power grid.
