Flyback reflected voltage
WebDec 18, 2024 · The flyback converter is an indirect energy-transfer dc-dc converter: first, during the on-time, it stores energy in the primary-side inductance and, because of the diode, the secondary is decoupled from the primary. In this configuration, the voltage … 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.
