please answer number 10 

The following forward converter (for questions 8-12) has the following parameters. Vin=40V, Vout=10V, Pout= 50W. The duty cycle is 40%. The primary side winding Np has 16 turns. NT: Np: Ns Vsupply D. AD: Vout Load C D3 A Switch S (Draw the circuit with Visio) 9. What is the turns ratio between the primary side and the secondary side winding? A. Np: Ns = 16:10 B N,:N= 16:5 C. Np:Ng = 16:7 D. None of the above 10. Assume the auxiliary winding NT has 20 turns, what is the maximum voltage on the power switch? A. 40V В. 72V С. 80V D. None of the above 11. Still assume the auxiliary winding has 20 turns, what is the maximum voltage on the diode D1 and D2? А. 10V, 10V В. 20V, 25V С. 25 V, 25V, D. 20V, 20V 12. For the above Forward converter, which of the following auxiliary winding designs will ensure fully transformer core de-magnetizing in every switching cycle? A. NT= 12 turns B. N= 30 turns C. N= 50 Turns D. All A, B, C are ok
