19.3: Resonant Tank
Is the resonant tank, all though a dual of the series resonator, acting with the characteristics of a parallel resonant tank? I think this is what dual implies........the dual of series network is a parallel network.....
19.3 current fed bridge is dual to the voltage fed bridge in the series resonant converter
- current fed bridge: current(square wave) is driving the resonant tank and the tank response is the voltage(sine with the phase shift) - series resonant converter: voltage(square wave) is driving the resonant tank and the tank response is the current(sine with the phase shift)
So I think your saying what I'm trying to say.....the actual analysis of the resonant portion of this problem should be exactly the same as what is outlined in the text for a parallel resonant converter?
That's what I'm thinking....H(s) will indeed be different. Although the resonant tank is in series, the output of the tank (sinusoidal voltage from capacitor) is driving the rectifier (i.e. action of a parallel resonant converter).
You may use this blog as a tool to post questions and comments related to Spring 2012 ECEN5817 homework problems. However, simply posting your solutions or copying someone else's work is not allowed - all work you turn in must be your own. Absolutely no collaboration in any form is allowed on exams.

Nice perspective above....
By the discussion above then M will come out to be the same form as for PRC case except magn(H(s)) will have different value?
