Hi
Hope you be well
i have designed a flyback converter with specifications of Vout = 24v , Iout(max)=3A and Fs= 65KHz. when 40w load is connected to the output of the converter, transformer gets too hot in a short time. (about 85C in the room tempreture of 30C)
the core that i have used is EC28*28. i have inserted 1mm airgap on the middle leg of the core and i have used 3*0.4mm wire for primary and 2*.6 mm for the secendary winding. the inductance of the core is 300uH and the PWM controller is NCP1288
can anyone help me with my problem please
