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. 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.
