Abstract :
High power electromagnetic pulses are of importance in a variety of applications such as transient radar, when investigating the effect of strong radio-frequency impulses on electronic systems and modern bio-medical technology. The paper presents details for a compact, battery powered, repetitive pulser, which is capable of producing nanosecond rise-time pulses at voltages exceeding 0.5 MV. The system is based on a Tesla transformer operating in a dual-resonance mode, with a high energy transfer efficiency between the primary and secondary circuits. To obtain a high pulse repetition frequency of at least 1 kHz, the key component is a closing switch in the primary circuit working on the principle of corona stabilization
