Abstract: The present invention is a device using a non-linear capacitor and voltage amplification effect, which can generate a pulse having a short pulse width at high voltage. The device comprises a rectification circuit for rectifying the AC input power supply, a semiconductor switch connected to one output terminal of said rectification circuit, a primary coil connected between an output of said semiconductor switch and the other output terminal of said rectification circuit, a diode in which the cathode thereof is connected to the output of said semiconductor switch, a capacitor connected between an anode of said diode and the other output terminal of said rectification circuit, a secondary coil in which one terminal thereof is connected to the anode of said diode, a non-linear capacitor connected between the other terminal of said secondary coil and the other output terminal of said rectification circuit, and a load connected in parallel across two terminals of said non-linear capacitor.

Abstract: A rotary arc gap (RAG) switch capable of handling large amounts of current flow is disclosed. The circular electrodes of the switch incorporate the use of a high-resistance material placed in a gap in the electrodes. The absence of an air gap in the electrodes reduces wear and broadening at the edges of the gap and thus improves the life span of the switch. Further disclosed is the use of a dual trigger mechanism that also improves the life span of the electrodes and the triggers.
