1 Objective:
Design a 50 W flyback converter with maximum ripple in output voltage as 1.5 % of output
voltage.The converter is working in continuous conduction mode for a load variation of 10 W to
50 W.Parameters of the converters are input voltage (Vin) = 5 V, output voltage (Vo) = 10 V,
switching frequency (fs) = 200 kHz, N1 = N2.
2 Flyback Converter Design:
2.1 Filter Capacitor
• The capacitor value is calculated using the given output voltage ripple as 1.5%:
∆Vc =
∆Q
C
=⇒ 0.05 ∗ Vo =⇒ C =
