Calculate:

  1. Calculate transformer ratio(N2/N1) (Round your answer)
  2. The recalculated duty ratio of the switch  
  3. Average inductor current ILX in ampere   
  4. The net change in inductor current ILX in ampere
  5. Value of inductor LX in µH (Round your answer)

Calculate transformer ratio(N2/N1) (Round your answer) – 0.8
 
The recalculated duty ratio of the switch – 0.28
 
Average inductor current ILX in ampere – 3.125
 
The net change in inductor current ILX in ampere – 1.25
 
Value of inductor LX in µH (Round your answer) – 92
