Hi,

Let's say i have a transformer with a turn ratio between the primary and secondary winding of 3:1. If i put a capacitor between the two windings, how do i go around analyzing the circuit?

Thank you.
 
i feel that the cap behaves like an addition to the inter-winding capacitor.when you represent a trnsformer, you will show interwining capacitance also-- this may add up to that value.
 
hi wakiki

Do you have a sketch on how this capacitor is connected and also what value
of capacitor, etc.
 
Don't do that, it's called a "Flux" capacitor and will break down the laws of time and space. You could damage your space-time continuum, maybe even erase yourself from history.
 
hi oznog,

In the 'olden' days the word 'flux' had a totally different meaning!.

If you had the 'flux', you were in deep s**t, literally.

Regards
Enjoy your Easter
 
A quick scan of a textbook shows that a good equivalent circuit of a transformer includes the ideal transformer in the middle with additional ideal components added to the primary and secondary. On the primary is a shunt R and a shunt L. The shunt R represents the core losses, while the shunt L is the primary self inductance. Then there is a series reactance (inductive) which is the primary leakage reactance preceded by a series R which is the primary winding resistance. Now, on the secondary side ther is a series reactance (inductive) which is the secondary winding leakage reactance followed by a series R which is the seconary winding resistance.

If you put all these elements into a simulator and then attach your load capacitor and assign reasonable values for everything, you will be able to analyze the effect.
