hi
The following are the design spec of a flyback converter given in the attached file (at page 13).
VIN: 28 V
Output 1: 5 V
Full Load Current: 10 A
Circuit Topology: Flyback, Continuous Mode
Switching Freq, fs: 100 kHz
Desired Duty Cycle: 0.5 at 28V input
Max Ripple Current (delta)lpp: 5 A @ 32V (secondary)
Peak Short-circuit Current: 25A (secondary)
Secondary Inductance, L: 6.8 uH
Max Loss (absolute): 2.0 W
Max Temperature Rise: 40°C
Cooling Method: Natural Convection
I need explanation of the Max Ripple Current, (delta)lpp: 5 A @ 32V (secondary). How ripple currents are defined in flyback converter and on which factors they depend?
