Abstract

A high-voltage waveform generator comprising a power source, a transformer unit comprising a magnetic core, attached to the power source, a plurality of power switch cards, each having an aperture that allows said magnetic core to pass therethrough, one or more control switches located on each power card, and a control means for actuating the control switches, a power output; wherein the power switch cards are connected in series, wherein each of the apertures in the power switch cards is surrounded by conductive windings, whereby when the power source is activated, the magnetic core induces a current in each of the conductive windings, and wherein the control means activates the control switches simultaneously in under 100 nanoseconds to generate a pulse.
