HW11, pb 2

Hello All,

In pb 2, how steady-state value of clamped capacitor Vs be estimated ?
In forward converter, we can estimated as if it is operating as PWM.

However, on flyback, if I use the same procedure (PWM), I end up
with Vs equal to V/n, which is going to violate ZVS condition for Q2.

Thanks,
Tanto

The problem states that Vs is "slightly greater than V/n." That is all you need to know about Vs, I think.
