Abstract
The application of dc voltage stabilizer very extensive, quality excellent dc voltage stabilizer can meet the requirements of electronic now, so, dc voltage stabilizer design are important, especially the numerical control dc voltage source this paper mainly introduces the numerical control dc voltage source design, be single chip puter control technology digital, organic integration into the dc voltage stabilizer design, can design a high ratio of performance multi-function digital general dc voltage stabilizer
This paper discusses the AVR16 based on single chip puter as the core control based on the numerical control dc voltage source design principle and method, the power supply voltage preset with adjustable output voltage signal and the voltage signal can also shows that this system mainly include LCD1602 display module 4 * 4 matrix keyboard module power amplifier circuit (the push-pull output), and auxiliary power + 15 V,-15 V, + 5 V
The design of C dc voltage source and the traditional manostat, it is characterized by easy operation voltage stability high characteristic, the output voltage size using digital display numerical control dc voltage source research unit in laboratory of industrial production line, in practice, there are many advantages, deserves further study and research
Keywords: a single-chip puter, numerical control, LCD1602
