Advice for Mains AC PCB
Hi I'm making a step down converter PCB in orcad allegro, that will be directly connected to mains AC. My main doubt is what connector pcb footprint could I use for that.
Specs are:
Input
Mains AC: 220V RMS, 50Hz
Load: Something around 500W
Out
FS=10Khz
full DC range
4A Maximum DC current
It's just experimental so, no protections will be used. Currently I put on the output and mains connector a TO-220 Footprint. I know it's undoubtedly insufficient.
My current schematic is this
I've made an artwork, with controller aux source included. What you think about AC or DC power Traces? (upper side, left side)

Please put 1M resistors in parallel with C10 and C11. It is not wise to let those caps charged after you unplug everything and touch the board.
