Abstract:Summary in a variety of electronic experiment, power is the most basic of needs. Design of a high precision power supply not only to meet the requirements of electronic experiments, and can meet the needs of different experiments using different voltage values to test requirements.
This design has a high-precision DC power supply. The power transformer, Rectifier, voltage regulator circuit, filter circuit, circuit protection, show circuits and other components. Display circuits using MAX136A/D conversion circuit.
With the development of modern science and technology, a variety of electrical, electronic equipment has been widely used in daily work, technology, learning and other aspects. As electrical power, energy supply of essential parts of electronic equipment, increasing demand, and power features, stability, and other indicators are also put forward higher requirements. Research and development on power has become the new technology, new device developed significant links, and plays an important role in promoting the development of science and technology. In order to meet the electronic industry demand for DC power supplies, this paper is to discuss the design of a high quality, economy, appropriate, reliable, reasonable, stable DC voltage-stabilized power source designed for the purpose of thesis. DC power supply planning of scientific and rational, guarantee all of the electronics industry continues to grow with DC power supply needs! a development of e-business and anticipating, do so, proportionally, to sustainable economic and reasonable. Ensure the quality of DC stabilized power supply, also, to provide adequate, reliable, reasonable and stable market, and economic power.
