I have a problem with arc of AC 220v supply while switch off AC load. I use transformerless power supply for my PIC16F as in picture below. If no AC load, PIC16F work OK. But when work with AC load and while I switch off or plug out AC load it make my PIC16F reset. So how to solve this problem to protect my PIC16F from reset, Please my expert friend?
