Self contained source based on an innovating resonant transformer and an oil peaking switch

Nowadays, a broad range of modern industrial applications brings the necessity of compact high-power electromagnetic wave generators. Conventionally, this kind of generator consists in a primary energy source and an antenna, separated by a power-amplification system that forwards the energy from this source to the antenna. A Marx generator or a Tesla transformer is classically used as a power-amplifier. Our structure uses an innovating very compact resonant transformer. Our complete pulsed power source, named MOUNA, is composed of a set of batteries, a DC/DC (300V/10kV) converter to load four capacitors with a 0.4A current, four synchronized spark gap switches, a resonant transformer generating a few hundred kV and an oil peaking switch. The design of each stage of our device is explained hereafter. This article presents then the mechanical design of the complete pulsed power system and the first electrical measurements (particularly concerning the resonant transformer output waveform, the line oscillations and the radiated E-field).
