吼吼~~感谢PO和Peekboo,初稿已经出来了,大家在帮改改:
With the development of modern science and technology, various kinds of electric appliances are more and more high to the power source request. The technology of power source has become an independent electronic research subject. Many kinds of electronic circuits require Direct Current power supply(DC), although DC supply can be provided by battery cells, a more economical and practical way is to convert Alternating Current supply into Direct Current source. Direct Current Voltage-stabilized source may by the discrete component constitution, also may by the integrated circuit constitution; May use traditional power transformer way, also may select a popular method of Switching Power Supply. What this paper involves is Direct Current Voltage-stabilized source which designs by using the integrated manostat. This way has the merit of manufacture simply, stability higher, the cost is low and so on.
The main contribution of this paper are :
1. Briefly introduce the power source technology background and the general principle of power source transforms.
2. Elaborated the Direct-Current Power Supply system constitution and its the principle of work.
3. Analyzed this system’s technical difficulties, keys and the special spots.
4. Designed and has analyzed many kinds of protective measures, including overcurrent protection, overvoltage protection and excessively hot protection.
5. Analyzed and has solved in the design process certain technical questions.
6. The Computer Simulation System(EWB) has carried on the system test and the analysis.
