EHT Inductive Adder for Nanosecond-Scale High Voltage Pulses into Low-Impedance Loads

EHT inductive adders allow high voltage pulses into 50 Ohm loads with rise times on the nanosecond-scale. This topology has the following benefits:

Case study, Office of Naval Research (ONR): the intent is to drive non-linear transmission lines (NLTLs) producing high power microwaves. 35 kV pulses were produced with adjustable pulse widths (40-100 ns) and fast rise times (11 ns). Short bursts were demonstrated at prf up to 1 Mhz.
