The compact EHT Nanosecond Pulser Inductive Adders (NSP-IA) generates high voltage pulses with fast rise times into low-impedance loads . EHT originally developed these to drive nonlinear transmission lines (NLTLs) for high-power microwave production for the Office of Naval Research. Today, these pulsers are used in a wide range of applications including accelerator physics, pulsed power research, water decontamination, plasma control, pulsed radar systems, and high-power microwave production.
Each NSP-IA offers the user independent control of the output voltage, pulse width, and pulse repetition frequency. The inductive adders ship with an external DC power supply that allows the user to control the output voltage and average power of the pulser.
To address corona and heating issues in the cable for the highest voltage inductive adders, EHT developed a custom SF6 filled cable that safely enables high voltage operation at high average power.
