Hi Friends.
Please suggest me method of calculation of output capacitor and LC filter for dc-dc flyback converter.
Specifications for my application are:-
VINmin=8 Vdc, VINmax= 20Vdc, switching frequency=100Khz
All outputs are isolated from each other & input. dv/dt swing ≤ ±5V/μs, Variation ≤ 2V peak to peak.
Output details are:-
1. SUPPLY1(VA-GND1) 15V 100mA
2. SUPPLY2(VA-GND2) 15V 200mA
3. SUPPLY3(VA-GND3) 15V 50mA
4. SUPPLY4(VA-GND4) 15V 50mA
5. SUPPLY5(VA-GND5) 15V 50mA
PWM controller used= UC2843
Feedback is taken from supply1.
Thanks in advance.
