Abstract

In this paper, a triple resonance pulse transformer based on a magnetic core transformer is developed, which uses the first peak of the output voltage to charge the load capacitor. A compact magnetic core pulse transformer is developed, which uses an innovative bi-conical specific geometry. Based on this magnetic core pulse transformer, the triple resonance circuit is built by adding a tuning capacitor and a tuning inductor between this transformer and a pulse forming line (PFL). The tuning capacitor is designed to be an irregular coaxial capacitor with a capacitance of 70 pF and the tuning inductor is made as a single-layer air core cylindrical inductor. The experimental results indicate that the peak output voltage of the triple resonance pulse transformer is about 530 kV and the rise time is about 790 ns. The peak voltage across PFL is 1.6 times the peak voltage across the magnetic core transformer. It is feasible to develop a magnetic core pulse transformer into a triple resonance pulse transformer.
