Power supplySimulation modelIn this work, the design and development of a new variable linear power supply, using the LM317 regulator, is proposed. The originality of this power supply is related with the control of the rectifier circuit, which is based on a reference of voltage, superimposed ...
用LM317和UA741制作的0-±15V稳压电源,LM317+UA741 Power supply 关键字:LM317,UA741,稳压电源电路图 本文向大家介绍一款能够从0起调的跟踪式稳压电源,由于采用LM317和LM337三端可调集成稳压器,故内部有限流、短路和热保护等完善功能。其独特之处:仅用一个单连电位器即能实现正、负电压“同步”调节,具有线路...
利用车内电池的USB电源插座,LM317-5V POWER SUPPLY 关键字:LM317,5V 如今有不少便携式电器普遍使用USB口作为其电源插头,例如便携式阅读灯就是用USB口来对其内部电池进行充电,但这种耗电较大的小电器利用电脑上的USB口就不合适了。对此.这里提供一种USB电源插口,它可利用汽车内部的12V电池来对使用5VUSB口为电源的...
因UR1为恒定电压1.25V,Rl是一个固定电阻,所以IR1是一个恒定的电流。另一路是317调整端流出的电流ID,由于型号不同(例如LM317T、LM317HVH、LM317LD等),生产厂家不同,其ID的值各不相同。即使同一厂家,同一批次的LM317,其调整端流出的电流ID也各不相同。 LM317电源电路本身具有60dB以上的输入纹波压缩度,采用下...
用LM317+TL081制作0-12V/3A可调稳压电源---LM317+TL081 Adjustable power supply 2013/12/26 17:22:29; 来源:华强电子网 作者:华仔 浏览:2689 时间:2016-08-10 14:18 标签: 摘要: 通常我们的电源不能从零伏起调,这里介绍的电路可以从0-12伏连续可调,且电路简单、取材容易,易于仿制。很适合业余电子...
