PSU

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.

Goals

• Can regulate it is voltage output
• Can current limit it is output
• Can be controlled over uart

Hardware

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.
