My take on a avr controlled powersupply that is variable.
Im going to use a transformer that I got, it is a 2x18V @ 1.8A. I also got a 230V input filter that is going to be put on the input before the transformator.
- Can regulate it is voltage output
- Can current limit it is output
- Can be controlled over uart
For development Im going to use a cheap china arduino uno, which is using a atmega328p.
Im going to use 2 - 3 ADC's on it, one for sensing the current that is being used, one or two for sensing the voltage used.
