Also show actual pictures or drawings of the CT: including core type, number of turns, winding method, etc.At no load condition[When the H bridge output is not connected to the isolation transformer]
@c_mitra : I did add a capacitor after the diode rectification. For this I changed value from 1nF to 10uF with no effect on the spike amplitude level. I have to check if the core is saturating at max current. If I am not wrong changing the current from min to max limit, correspondingly there should be a change in voltage on the secondary after rectification will tell if my current transformer is getting saturated or not.
Specified frequency response 2Khz to 200 Khz
You mentioned your switching frequency is 50 Khz, the core will be reset every 20uS, it never sees 50 Hz.This is certainly not intended for measuring current in the 50Hz range; but I certainly do not know the anatomy of the beast but they are most likely useful for pulse transformers for signaling use- just like an opto isolator. I do not know (but doubt) their linearity.

@c_mitra : based on your comment, I see using off the shelf current transformer doesn't work for H bridge configuration ? Could you clarify on that ?
It will probably be a lot easier to source a ready made transformer than source a suitable very high permiability ferrite toroidal core, and quite possibly cheaper as well.I am planning to buy transformers available in my country. Custom application in the sense, I want the secondary voltage to 1.2V @ 5A rating instead of linear output of 5V for 5A. I think I will find a way around using a bunch of resistors.
That looks like an excellent choice.: CS4050V-01L. Can you help me out if I can use this for my application ?
Can you please explain how you calculated the voltage at which it will go to saturation ?
