I have a mains-rated transformer that is a leftover part from my previous project. Now since I am experimenting with the idea of SMPS, I am wondering how it would behave when handling the higher frequency of a SMPS. Does this spells a higher capacity?
The transformer in question is rated for input of 220V 50Hz, outputs 12V and have a rated capacity of 3VA. What happens if I try to put it in a SMPS with an operating frequency of 150kHz? Will it catch fire?
