Modeling of coupled inductors?
Mar 13th, 2015, 1:37am
 
Hi,

how can we model e.g. in verilogA coupled inductors efficiently?
I also wonder about a special topic: It is wellknown and simple to transform a pair of coupled inductors (i.e. a transformer) into a T-circuit. But is this also possible with 3 or more coupled inductors (all grounded at one side)?
Found nothing in the internet unfortunately.

Bye Stephan

Are the inductors themselves in Verilog-A, or do you just want to model the coupling in Verilog-A?  I'm not aware of a way to pass the instance names of external inductors into a Verilog-A module to do the coupling.

If you're doing everything in Verilog-A, the only thing I'd caution you about is to make sure the scaling is done properly.  Think about what the unknowns are and how the simulator tolerances will apply.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
