Hi...
I want to know how to calculate the values of inductance and capacitance value?
This question comes up fairly often in Nuts & Volts magazine - the columnist who does the Q&A pages has got pretty well practised at trotting out the formulas every few months.
 
Hai guys i designed flyback converter its input is 127 to 400V and output is 24V when i give 127V its 24V output but if i change the input output also change and i check compensation circuit its ok i don't know why

transformer winding is 38:09 and Lp is 228uH and output capacitor is 560uF and Ro is 4ohm and in error amp type 2 is R1 is 1 and R2 is 10 ohm and c1 is 10uF and c2 id 1uF.
