tom_supertramp Posted February 17, 2011 Report Share Posted February 17, 2011 Hi everyone!,I'm a new member of the site. I currently have got a serious problem.I'm an electronic student yr3 in Viet Nam. In my University don't have many material related to design electric circuit. Just only a few slide prepared by lecturerer at classes. But the teachers' requirements are so high.So it makes me really confused about projects that they gives me. If any one has any materials regarding designing (how to determine value of resistor,capacitor, choose BJT ,etc) and analyzing circuit plsease do me a favour by sending Link(ebook) or name of book which is avaible for dowload. Many thanks for concerning Email removed by moderator. Quote Link to comment Share on other sites More sharing options...
tom_supertramp Posted February 18, 2011 Author Report Share Posted February 18, 2011 Thanks George,I think I should post the titile of my project here then everyone can help me easier.My project is about design a dual power supply circuit +-12V 5A with over voltage protection.

audioguru Posted February 18, 2011 Report Share Posted February 18, 2011 You have a lecturer and a teacher. They have failed their jobs because they didn't teach you how to design your power supply assignment.Teachers and lecturers in most countries actually teach electronics to students so the assignments are done correctly, not just copied from somebody else.It sounds like you do not know the simple basics of electronics. After you learn the basics then you can learn how to design simple circuits. Then maybe later you can design your power supply. Quote Link to comment Share on other sites More sharing options...
Hero999 Posted February 18, 2011 Report Share Posted February 18, 2011 I'd use a nice chunky 200VA 15V-0-15V transformer, a 5A bridge rectifier, two monster 10,000 Quote Link to comment Share on other sites More sharing options...
tom_supertramp Posted February 22, 2011 Author Report Share Posted February 22, 2011 Thanks all you guys, Your hints are very useful for me, I'm reading and combining them with some books I've collected to solve my project. In next few days, if any difficult issue occurs during designing time, I will still need your help^^. Quote Link to comment Share on other sites More sharing options...
bajgik Posted February 22, 2011 Report Share Posted February 22, 2011 Check this tutorial on basic electronics, that might help.... http://www.electronics-control.info/basicelectronics.aspx Quote Link to comment Share on other sites More sharing options...
