A high voltage pulse transformer with a magnetic core which is biased by d.c. current in the direction opposite to the pulse magnetization has been developed. Pulse characteristics of core materials are studied in two cases of with and without d.c. bias. A pulse transformer for. a klystron amplifier with a step-up ratio of 13:1, the pulse duration of 4 μsec and the secondary peak voltage of 150kV has been constructed. Rise time of 0.3 μsec and linear droop of less than 1.5%/μsec are obtained.
