Every electronic gadget primarily needs a D.C, power supply to energize it. It also forms the basic requirement for any constructional project. consequently there is a need to obtain multiple voltage values for cost...
message: Hi, i’m looking at building a power supply 0-35v ,0-100A adjustable cv and cc. I stumbled across your circuit drive-scr-thyristor-with-555 is there a link to describe what phase logic is required to complete the...
In this circuit the 12 DC, two wire is converted to three wire +5 and 0 and -5 dual supply useful for op-amps or other interface circuits. You could use 7805 and 7905 low...
This was a common way LM317 was used to get a stable power for small devices. It is still useful for learning and some blocks of the circuit are still used today in modern...
I will just explain part of this circuit. D9 and D10 provide a low cost -1.4 from -5 V. This is needed to reach near 0.00 for LM317 Min. setting. An LED also can...
This circuit uses a PNP Power Transistor TIP2955, you can use any other according to your current and voltage requirement. Look at R2 a 10 Ohm resistor, when the current in your load to...
This board provides 5 volt or 13.8 volt power. may be built up as a 5 v/13.8 v dual power supply. This board has LM317 and make a nice Laboratory bench supply. Thanks...
message: Hello, I want to know the single IC which can provide Both + V and -V from a single +Vin supply.. I need this for my dual supply opamp.Reply me as soon as...
HELLO THERE …COULD anybody pls help me with a place to get more information on the following components…cant seem to find it anywhere. W20NB50 W8NB100 found them in a liteon power supply pack for...
This is a a circuit from my Power Supplies Section. There may be some documentation errors in my circuits. If you are used to building and troubleshooting circuits then it is ok. This circuit...
This is a SMPS Circuit improved over the Application Note in the book SGS Motion Control Application Manual. This worked well. It helps you learn more about High Frequency Power Supply Design.
(This is a thread of my messenger many years ago – you will be able to notice text communication is quite difficult. sometimes even verbal expression will not specify the need, We need clear...
