Analysis of pulse transformer by distributed parameter theory

The pulse responses of magnetically coupled pulse transformers of arbitrary turn ratio n:1 are considered in the framework of a distributed parameter theory. Equivalent circuits for the calculation of pulse risetime and flat-top responses are introduced for inverting- and noninverting-type transformers, respectively. With these equivalent circuits, the pulse risetime responses are calculated more precisely than with the lumped-parameter circuit theory. Measured responses of pulse transformers agree well with the theoretical predictions
