Design Of Pulse Oximeters Torrent What Are Techniques To Minimize Leakage Inductance Of PULSE TRANSFORMER? What Other Factors To Control?

What are techniques to minimize leakage inductance of PULSE TRANSFORMER? What other factors to control? - design of pulse oximeters torrent

I designed pulse transformers, where the pulse width varies in a range of 5usec-600usec (square). What are the design parameters that control?
I came to know that the capacity and the leakage inductance is very critical for the pulse transformer. How do I manage them?
I am also facing the problem of the lack of availability of materials for the quality
Plz help me and give me useful links or know about.

Thanks
