Flyback Transformer Inductance
Estimate primary inductance and current for an initial flyback design.
Input parameters
Results
Check core saturation, losses, insulation, and control limits.
Model & assumptions
DCM: Lp = η Vin²D²/(2Pout f); Ipk = Vin D/(Lp f); demagnetization fraction = Vin D / Vreflected.
DCM energy-balance estimate only. Complete demagnetization must fit in the off-time. Verify core flux, turns ratio, leakage and controller limits separately.
