ABSTRACT
This paper is on the integrated-steady power with a digital. Pass by the analysis chooses to use to establish a line steady press power supply, it adopts negative feedback principle to carry on steady press direct current steady press.That project can attain an electric voltage adjustment rate,efficiency and output the index sign that the electric voltage can adjust.But, that electric circuit is the line is steady to press power supply, adjusting a tube a work Be enlarging area,the pipe consumes to compare greatly, so the exaltation of efficiency is a hard nut to crack.The integrated-steady voltage employs a three ports steady voltage integrated circuit it can be change contionously and output steadly The portion of digital display employs the reference power and 7/2 bit A/D translator etc.The steady power has many adrangtage such as steady fanction simple strecture and high precision etc.Some figures show a baseline voltage power. 7 Road Darling Woods drive arrays. Front Suocun / decoding / drive and the total cathode led luminous digital control circuits, such as achieving voltage figures.
Should be adjustable steady press power supply to have the function stability, but the structure is opposite simple, the electric voltage index sign accuracy is high, regulating convenience, output can see to turn, the power consume low, the power utilization is high to wait an advantage.
