i designed a flyback transformer which is working in discontinous mode...
why does oscillations happens across drain to source of mosfet on the primary when secondary current goes zero?
and the output voltage drops drastically as load increases , its output is like 8v at load current 0.9A which was designed for 25 v at nominal load current of 500mA.
what could be the reasons?
