Abstract
This paper studies and designs a multi-functional digital regulated power supply, which can realize the switch between the two functions of numerical control current source and numerical control voltage source, and can set the relevant current parameters and voltage parameters through the keyboard. The idea of feedback control is fully adopted to establish the internal and external double negative feedback structures, so as to improve the precision of the regulated power supply. The digital regulator has the advantages of convenient control, large amount of display data, stable performance and so on. It is suitable for various applications of small capacity power supply.
Highlights
With the rapid development of electronic technology, the application of the power supply is more and more widely, the types of power supply on the market are very complete, it is rare to find a power source with the advantages of switchable current/voltage source, adjustable output power parameter, simple peripheral circuit, high reliability, low cost and so on
This paper designed a digital regulated power supply based on feedback control, which can control the output of current/voltage source through the keyboard, the power supply has the function of adjustable output parameters
It is believed that it will bring a lot of conveniences to all kinds of experiments that need power supply
Summary
With the rapid development of electronic technology, the application of the power supply is more and more widely, the types of power supply on the market are very complete, it is rare to find a power source with the advantages of switchable current/voltage source, adjustable output power parameter, simple peripheral circuit, high reliability, low cost and so on. This paper designed a digital regulated power supply based on feedback control, which can control the output of current/voltage source through the keyboard, the power supply has the function of adjustable output parameters. This kind of power supply has perfect function, simple peripheral circuit, high reliability, and can be used by students and researchers. In order to make the design reach the above mentioned characteristics, the overall design scheme and hardware design principle are discussed in detail before the design
