Classification of Regulated Power Supplies
Regulated power supply is its output voltage is relatively stable, it is closely related to people's daily life, also known as stabilized power supply, voltage regulator. With the development of electronic technology, the application of electronic systems is more and more extensive, the types of electronic equipment is also more and more flexible and diverse requirements for regulated power supply. The miniaturization and low cost of electronic equipment, so that the regulated power supply towards light, thin, small and high efficiency direction. Design, regulated power supply also from the traditional transistor series adjustment regulated power supply to the high efficiency, small size, light weight switching type regulated power supply rapid development.
In daily work, electronic engineers usually according to the stabilization object of the regulator in the regulated power supply, the regulator is divided into two kinds of DC regulator and AC regulator, and the output voltage of the DC regulator is DC, and the output voltage of the AC regulator is AC, and both of them are generally powered by utility power. Therefore, we can regulate the power supply according to the type of regulator can be divided into two categories of DC regulated power supply and AC regulated power supply. Below we have a brief introduction to these two categories of voltage stabilized power supply.
The classification of regulated power supply does not have a clear meaning and boundaries, we can also classify the power supply according to the other characteristics of the power regulator. In the face of a wide variety of power supply products, how to choose a suitable voltage stabilized power supply is very important. We choose a voltage stabilized power supply, in addition to determining the model and type of power supply, but also consider whether the electrical characteristics of the selected voltage stabilized power supply can meet the needs of the work. An ideal regulated power supply, in addition to power and output voltage and other basic indicators to meet the needs of the work, for AC regulated power supply, we also need to determine the number of phases of regulated power supply, regulated range and regulated accuracy, also need to meet the needs of the work. For DC regulated power supply, we need to consider the regulated power supply power adjustment rate, output power, load adjustment rate and ripple and other indicators.
