开关电源毕业论文外文翻译

童鞋你好！这个估计需要自己搜索了！网上基本很难找到免费给你服务的！我在这里给你点搜索国际上常用的外文数据库：---------------------------------------------------------- ⑴ISI web of knowledge Engineering Village2 ⑵Elsevier SDOL数据库 IEEE/IEE(IEL) ⑶EBSCOhost RSC英国皇家化学学会 ⑷ACM美国计算机学会 ASCE美国土木工程师学会 ⑸Springer电子期刊 WorldSciNet电子期刊全文库 ⑹Nature周刊 NetLibrary电子图书 ⑺ProQuest学位论文全文数据库 ⑻国道外文专题数据库 CALIS西文期刊目次数据库 ⑼推荐使用ISI web of knowledge Engineering Village2-----------------------------------------------------------中文翻译得自己做了，实在不成就谷歌翻译。弄完之后，自己阅读几遍弄顺了就成啦！学校以及老师都不会看这个东西的！外文翻译不是论文的主要内容！所以，很容易过去的！祝你好运！

Abstract:Switching power supply with high efficiency and other characteristics of light are widely used in many fields, a huge market. This paper describes the classification of DC / DC converter main circuit analyzes the push-pull DC / DC converter is constituted, at the same time gives the internal structure of the SG3525 chip and pin functions, a detailed analysis of its features and works , with its design of a push-pull adjustable duty cycle DC / DC switching power supply. This paper presents the design method parameter calculation circuit and the main unit of the circuit, and the power performance test. Experiments show that the power supply with high efficiency, high voltage adjustment, output voltage stability and so : switching power supply; SG3525; Push-Pull DC / DC converter; PWM
