WebMay 31, 2005 · • During the “off” time of the switch, the output voltage across the inductor is coupled to a new output via an added winding! • No free lunch. There must be enough energy stored in the choke to feed the new output. • Ampere-turns are preserved, so current drawn from the new output causes discontinuous current in the main output. WebDec 27, 2015 · The flyback voltage of the primary is simply: V f b = ( V s e c = 12.6 V) × T p r i = 30 T s e c = 5 = 76 V This does not account for the extra spike due to leakage inductance. And be aware that as seen by the MOSFET, this is added on top of Vin, the rectified input voltage.
