I have a DC-DC flyback, which has a 47uF, 450V bypass capacitor at the input. What would happen if I connect a 220 V AC supply at the input instead of DC? Will the bypass capacitor blow off? Or, or will I see some other effects on the flyback board?

What would happen if I connect a AC input to a DC-DC flyback converter without any rectifier?
