Hi! I`m using 18F4431 to run a frequency inverter. So here is the chart View attachment microchip.pdf
So when the chart runs without the load everything is OK. But when I connect the engine after 2-3 seconds the controller resets. I measured the power supply and it drops to 2V. Can you tell me what else I can do to fix this???
Thanks!

hi,
Most probably a curent surge produces the voltage drop on ac main supply and your transformer has <1 VA power rating, try a different transformer 220/12 V ; 5VA ... or whatever standard type transformer that is greater than the one that you use now
