Hi, I have the same idea, but don't have time I uploaded some digitally controlled PSU found somewhere in circuit cellars. It was with 8051 familly uC... http://rapidshare.de/files/16789544/psu.zip.html

Here is another one that a PIC16F84 and you can control it by PC aswell it was pulished in elektor electonics. http://rapidshare.de/files/16819909/Digital_power_supply.rar.html I was in the process of converting it into Proton Basic but never got to finishing it of as ohter work kept me busy enjoy wizpic:o

I don't suppose you ever thought of finnishing it,I can't make head or tail out of the original code but in proton or pic basic maybe

Hi Jeanninemtv
As you sure know that due to large capacity of 27,28 xxx series , its programmer has to be PC interfaced ... use the link for the schematic, layout and part list for the Eprom Programmer you can use this link HEREHope that it may help in your important task :cool:

thanks faros & lumos. good grabber ... Hey Lumos,,, ONe question... one suggestion too have you tested on board yo' soft.... i tested it on proteus... cool ... workss there's no matter about the connection between of transformer and out of regulated psu..=? the author of the article for AVR says no problem but.-- i need another opinion... and second... you dont have any buttom to change the status to HI-Z (V=0 I=0 )to enable changes on V and I... on the real psu's on my faculty's lab this function is enabled... i think i can put any interruption (rbo i e. ) to make available. Good Good Work friend ... thanks

Hi Jeanninemtv
not only the software works also...the hardware. (see my picture)
I use tipping over nonlocking keys for it vote the voltage and the current. (Picture)
being used two Transformer
Powerpart: Transformer and Bridge Rectifiers DC IN Pin 1 = + 30V DC IN Pin 2 = Case DC IN Pin 3 = Ground
DC OUT Pin 1= Ground DC OUT Pin 3 = regulated Voltage
Regulator Part: 9V AC

lumos
your power supply looks cool and i like the LED readout one aswell Is the 7 seg meter done using a PC and in Proton code if so you want to share it with us I shall have agoat getting the power supply up and built soon, I was going to use your code to contorl a power supply that i have already built up 0-30v 0-10amps (velleman kit) and use op-amp has voltage doubler and basicily replace the pots but your design nice and simple cheers wizpic

thanks 4 the photo.... i still think that the 0V 0A state during the setup of the psu is good... i'll make an code and i will send you for review... thanks another question... i have a pic proggrammer compatible with epicwin, you know, the 7407 and the transistor on lpt... if i program an pic 18, i can read and erase an program it normally...? ther;e no problem? thanks

Hi Wizpic
my voltmeter as an attachment
to jeanninemtv
everybody is the last adjusted left to himself worth switch on.
pic18 burns my self-made epic without problems
the prog_plug in the shematic is for ICSP with bootloader and level adaptation to rs232 .
bye

Lumos I think everybody want's to make your power supply which looks really good in your picture very nice job.is it possiable for you to put all the files in one zip so everything is together and easier to keep track off thank's

Dear Lumos
Hi
I download schematic of PIC18f252 based power supply. It seems interesting, but some clarifications are required. I hope you clear them:
1. Crystal value?
2. Power transistor No.?
3. R2 to R17 resister wattage?
4. if we want to additional current , we add more transistor and what changes will be made in code?
5. PIC18f252 is not available; can we replace it with 16f876?
6. When we compile the code error will be display***Variable FLOAT_DISPLAY_TYPE** not define?
Please help me

Hello Munaf
for your questions
1. Crystal20MHz
2. Powertransistor 2N3055
3. Resistors 250 mW
4. the transistors with the resistors being included parallel to the other transistors ...
it has to be wondered whether a multiplier resistor would be advisable at the respective Basis for the purpose of operating point
5.are available two PWM hardwareoutputs if this is not a problem
6.Float_display_type is not a Variable. Is a "Declare" of Proton+
to increase the precision
I hope to have helped you
bye
