Question

5. The "offline" flyback converter shown in the figure below provides +12V and +5V outputs. Eachoutput supplies a

20W load. The transistor duty ratio is to be = 0.5

  1. What should N5 and N12 be?
  2. Ideally, what value of Lμ will ensure a current ripple (in iin) below ±10% with 50kHz
  3. switching.
  4. Simulate the above system in SimScape, and show me relevant simulations, in particular, the voltages across the 3 capacitors (there should be ~ 20W loads at the outputs).
  5. Optional: See if you can examine the effects of leakage inductance on the voltage regulation (see How to deal with Leakage Elements in Flyback Converters)
