Flyback Transformer Leakage Inductance, Part
2
Primary-to-Secondary Current Transfer
by Dennis L. Feucht
Innovatia Laboratories
When a flyback converter's primary power switch turns off, current is transferred from the primary to the secondary winding. This does not occur instantaneously and the transfer delay depends on the primary-side clamp voltage. This current-transfer phenomenon is examined here.
Flyback Circuit Current Transfer
Continuing from Part 2, a Zener diode clamp, with its simplified constant-voltage clamping characteristic, is shown in the flyback circuit....
