I am newbie in AC supply PCB design. I have designed the PCB similar to NCP1027ATX evaluation board link. This is the link to pdf of my board schematic. The problem is that, at the output, the voltage is fluctuating and so that the microcontroller and other circuitry at the output not working. I have also attached the PCB layout if needed.
