Nanosecond Pulse Generators

The Nanosecond Pulse Generator (NSP) series by Eagle Harbor Technologies (EHT) is available in either low or high power variants to easily drive capacitive loads, like dielectric barrier discharges and other low-temperature plasmas.

Low power units operate at 30 W, 60 W, and 120 W. High power pulsars operate at 1000 W, 3300 W, and 5000 W.

In a very user-friendly format, the three key output parameters of short pulses can be independently and continuously controlled by the user, on the front panel or by fiber-optic trigger. The range of adjustments are:

Adjusting these values gives the user excellent pulse control with high precision timing.

All units operate at a fast rise time of 20 ns. Dielectric capacitive loads vary from 0 to 100 A current output.

EHT NSPs achieve fast output repetition rates of ultra short high voltage pulses with continuously variable output pulse lengths. High voltage isolation is integrated into the design. The units can be controlled via a fibre optic gate.

A clean square wave form is produced, although the exact pulse shape depends on the load. Further, different pulse waveforms can be achieved by adding a magnetic compression stage.

The Spartan

The EHT Spartan is a high-power nanosecond pulser designed to bias electrodes, capacitive discharges, and grids often used in industrial applications such as semiconductor, accelerator, surface treatment, or water purification.

Spartan features adjustable waveforms by user controlled independent pulse repetition frequency, output voltage, and pulse width. This flexibility allows the user precision control over industrial processes. The Spartan system can be directly triggered by a fiber-optic triggers or with EHT's controller that can be configured with a variety of industrial protocols.

Water cooling allows high pulse repetition frequencies at high average power levels.


Spartan is designed to efficiently drive capacitive loads. The system has the following specifications:

Cooling requirement: Facility Water (or 7.5 kW and 200 kHz air cooled)


Product Spectrum

The EHT NSP range of nanosecond pulsers allows continuous and independent adjustment of voltage (kV), pulse repetition frequency (kHz), and pulse width PW (ns), apart from which it shares characteristics with fixed-value units from FID GmbH, particularly the FPG-N series, at a lower delivery lead time.

In the pulsed power category, Behlke Power Electronics GmbH make fast solid-state high voltage switches using MOSFET and IGBT technology.
