For the circuit shown with following parameters,
L=500uH,R=2\Omega , Vin is within the range of 8 V to 16 V , Vout is desired to be 80 V constant
Ts =200 us
Primary winding self inductance: l_(1)=500uHl_(1), with N3=N1, tertiary winding self-inductance
is also the same as l_(1) k_(12)=0.99998,k_(13)=0.99996, and k_(23)=0.99996
Draw the T-equivalent circuit of the forward converter
Calculate the mutual inductance, primary leakage inductance, secondary winding
leakage inductance, and tertiary winding leakage inductance that are shown in your
equivalent circuit
Given N1=1, ignore the voltage drop on leakage inductance, what is the minimum
number for N 2 to achieve Vout =80V (constant), and what is the duty ratio range of S1
for your designed N2
(2 points).
