I made a simple inverter 50W and is working satisfactorily. Can I parallel up two same spec transformers as shown in the schematic below? Or will the MOSFET blow-up due to backemf? Thanks.
There's no principical difference between using two 50VA or one 100 VA transformer. I doubt, however, that a single pair of IRF244 is good for 100 VA from 12V.
