I am planning to build a microcontroller power supply. Should be symmetrical, 0-30V and adjustable current limit.. both voltage and current limit controlled via D/A converters.
Anyone out here who already did something like this, or has some suggestions ?

Something like this in Elektor/Electuur of december 2001, using a PIC procesor.

If you can wait a while , i'll have the 2001 cd-rom , and i'll send you the article in english . Source is , as usual with elektor , not available . And since it's a pic , it can not be extracted . So you'll have to buy a preprogrammed one or write you own code .

PIC-SUPPLY-1.pdf and PIC-SUPPLY-2.PDF uploaded in FM1/Mitsuko .
Total size about 750 Kbyte .

As usual no code available . You'll have to buy a preprogrammed pic at elektor .
Maybe you PIC geniusses can reverse engineer it ?
If you do , let us know .

I join a project of a compact digital
power supply controlled by a MC68HC11A1P
and the RS232 interface of a P.C.
This power supply is done of 2 parts:
processor board and power board.
The microcontroller controls the alternative
voltage in the output of the transformer
then this voltage is rectified and filtered
to obtain a continuous signal of around 22V
from this voltage is stabilized two
voltages that will be references for the
regulation and the current sensing.
(...)
Characteristics
Preprogrammed voltages 1,5 - 3 - 5 - 6 - 9
- 12 - 15 V
I = 4A
If I Max = disjonction
RS232 control
Emission on serial line of voltage and
current
IC used :MC68HC11A1P @ 8MHZ , CD4016, MAX232,
2x16 LCD Display,LM324, 7805, 7818,
option Serial IIC EEPROM
Transistors used 2N3055, 2N2219,etc.
only the S19 SRecord file is available.
if interested in realizing it
I can translate this article into english
MB.
