Pulse Transformers

Abstract

If many electronics engineers regard magnetics design as a black art, then it is also true that many transformer engineers regard pulse transformer design in the same way. The reason is that a pulse transformer must faithfully reproduce the high frequency components of the leading edge of a rectangular input step, the low frequency components of the flat top of the pulse, and all frequencies in between. At the same time it must present to the source and load appropriately balanced parasitic components whose characteristic impedances match the source and load impedances.
