the pic and specifications have been added.... I will really appreciate if someone can help me to calculate the (duty cycle D; the voltage and current across transistor Q1, Q2, Q3, Q4; the voltage and current across diode D1 and D2; the output capacitance and inductance value........... Thanks....... I have already done all thoView attachment 4291

View attachment 4292se and have result in my excel that I can share if you want; but I am not sure about my result.

Hi Zhenif
welcome to the forums

I have moved this thread to the homework section where it is better suited :)

First, I have assume that each full Bridge converter there have the same duty cycle... Now for the duty cycle calculation, I have consider the following equation:
V=nDVg......... as the turn ratio is 1:6:6, I have consider n=6; and so, it resulted to D=V/(n*Vg)........ V=50; and Vg=120 and so =======> D=120/(6*50) = 0.4.... I am not 100% sure because in full bridge converter, we have twice the duty cycle so I am assuming that D finale is D=0.8.... can someone clarify me on that?.... Thanks
