WebSep 16, 2011 · Flyback transformer is better described as a coupled inductor. Energy is stored in magnetic field, charged by primary, discharged by secondary. A regular power … 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.

WebFor the example in Figure 1, the reflected voltage is 10V. The Zener is se- lected to be 12V (approximately 20% greater than the re- flected voltage). The maximum reverse voltage across D2 is equal to the maximum input voltage. This diode must be an ultrafast or Schottky diode to prevent excessive diode losses. Webvoltage drop on the power switch and on the secondary side diode. Eq. 2 is valid for any input voltage. The second design equation comes from the maximum power switch breakdown, defining first Vfly, the flyback reflected voltage, and then calculating the maximum switch breakdown voltage.
