I am confused about this equation.

The model makes sense. I see the correlation between M(D) which for a buck a converter is just = to D
The book talks about using an ideal transformer to allow the use of basic circuit equations in this case a voltage divider.

I have literally no idea where the M^2(D) term is coming from. Its just a voltage divider. I have done the algebra every which way i can think of and still cant get there.

Anyone else know where that M^2(D) term comes from?

 

hi mike,
It is the mutual coupling.
Look at this PDF.

I just found it in an old book i had. Got it now. Thanks
