Design of digital regulated power supply based on feedback control

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.
