If I have done any Mistake with my Power Supply.. Then can you Please Figure it out !!!! ??? ???
and I have also attested the Schematics of the Digital voltmeter
??? ??? ???
Hello,
Actually I am designing a Digital Voltmeter using ICL7107. Having capability to measure 0-200v with 0.1 resolution.
My Problem is, when I connect the output of 7805 and 7905 to ICL7107 at Pin 1 and 26
respectively. the output voltage become zero at the out pin of 7905 as well as 7805...
I know how to use Google
I searched too much ...but still didn't find any circuit which matches with my specification.
and I have Posted my Specification:
I need output in both negative as well positive mode
I need 5v positive as well as 5V negative (i.e; -5V)
and +10V and -10V.
If you can...
Hello Friends,
Actually After Making my PSU, Today I thought to make a SMPS.
But the Problem is this I have not the schematics of the SMPS. Can anyone here Give me the schematic for designing my SMPS.
My Requirement is below
Input Range Vac(in) :- 100v to 250v
Output Vdc (out) :- +5V, -5V...
Thanks Buddy.....For your Great suggestion, So, I will really work on your advice about power wiring + primary as well as secondary fuse + make the PCB more Neat and this time I gonna design it with a big chassis as it now....
Thanks buddy...again for your Great advice...... :D :D :D :D :) ;)
;D ;D ;D ;D
Don't Think Like a little baby ....Hero
I have tested it upto 4 hour of continuous in ON condition with a 500ohm of Load resistance.
Its was working fine for me
I am just using 1 amp of transformaer....but I can Handle upto 20A of current and 1 amp is nothing as compare to 20A...
Sorry Brother,
I have never used PSPICE, so I can't help you about pspice.....
But I will recommend you to use TINA electronics Lab....because Its having more funcation and well user Interfaced enviroments for simulation.
I am also using it ..Even I have also tested LM317 based power supply to...
I know it Looks dirty and even it can let anyone in confusion.........
I can Understand...Ok anyway ....Its all just because it was my first time when I made a PSU indivisiually.... :-\
thankyou audio guru....I have made a power supply using LM723.....I am a beginner right now...thats why I made this simple power supply and working fine for me...
Some pics of my power supply Is here :
and finally Circuit Diagram :
Hows Its
your answer take me to 2 different confusion...
1st
if the load resistance is 20ohm , then how 40v will flow through the load, so the maximum limit of Vout is just 30v.
2nd
if the circuit will do like this then how we will get our desired Vout at the o/p end, in this manner only one thing can...
One thing I still did not understand..... That
Current is depend on load resistance. by changing the Load Resistance only the current can be controlled.
Can you tell me, How we are controlling the current here ?
How we get the desired current output independently to load resistance here in...
:) Thanks for the tip.
I have Finally Decided to make this PS. plz tell me will it work fine as per my expectation
My requirement is 0-30v o/p
with 0-3A
Plz tell me
???
PS_Parts_List_10-11-091.pdf
So, Can u Give me any modified latest schematic for power supply
My Requirement is
Variable Voltage Output = 0- 30 V
Variable Current output = 0-2/3A
Actually, I had decided to make the Circuit shown in below post :-

But, When I...
