High Voltage, Low Inductance Pulse Transformer Using Ferromagnetic Core

Abstract

A New type of pulsed transformer is proposed to apply for pulsed power technology as an alternative of a Marx generator. The transformer is constructed of a coaxially shaped ferrite core and a spiral winding of strip conductor. Transformer of output voltage more than 1 MV is demonstrated to be possible to design with winding ratio of 10:1 and residual inductance of secondary winding of 2.5μH. The performance of the transformer is demonstrated by the example design of the system where output pulse of 1 MV, 100 kA, 50 ns is produced by using 100 kV of 1st stage capacitor bank.
