I am working on inductive coupling b/w resonators (RLC) ,using orcad lite 16.6 tool. At this time I am unable to perform it properly, Is any one there to suggest me how to couple the resonators via inductors? I am using "K_linear" under analog library ,as coupling coefficient. The circuit layout and model is attached:
>>>We have,out of total, 5 main couplings
>>>The cicuit layout shows this.
>>>Analog R L C are used
Hoping for a positive response.
Thank you for the reply..........
But I further need guidance, how to change the remaining couplings?
I have done this L1=L1l L2=L2r1 with the K1, (attachment), but how to change remaining K2-K6 with such expressions? Also check the property window pane of the schematic.. Is that correct??
Keep in mind that with more than two windings, there constraints on the values of k aside from -1<k<1. For example, if you have three inductors L1 L2 L3, then if you define k12=1 then k13 and k23 must be equal to each other (k23=k13).
Rather than coupling coefficients, you may find it more intuitive to model your coupled inductors with an impedance matrix Z.
Thanks for the guidance.... its working..
Now, I want to done the couplings which are >1 in magnitude.. HOW can I make it possible??
Is the inductors supporting k>1 mag, are different than normally used??
I have used a discrete type inductor..
Many CAD tools use both representations.
In my favorite tool it looks like this (Microwave Office / AWR):
With each new tool, the user has to take care of modeling.
I have to implement this one
Now how can I make such coupling within range 0-1. Moreover, I am just unable to understand N- N+ non resonating nodes here in the matrix...
