Power, Plasma, and Energy Technologies

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.

Electroporation is the application of an electric field that causes a brief breakdown of cell membranes to allow molecules to enter the cell. A primary biomedical application of electroporation is the reintroduction of engineered T-cells for immunotherapy.

The EHT Bipolar Microsecond Pulser (BMP) allows researchers and businesses to ablate cancerous cells, rapidly develop new cancer therapies and develop vaccines and other treatments. The BMP produces high-voltage square pulses with fast rise times.

This Integrated Power Module (IPM) by Eagle Harbor Technologies (EHT) simplifies high-current, high frequency, solid-state switching. The IPM features a solid-state switch, fiber optically isolated gate drive, freewheeling diodes, fast capacitors, snubbers, and crowbar diodes. It is housed in a 3U chassis.

EHT pulse generators are designed to provide precision control over the output waveform to enable process optimization. These units have an isolated/floating output and can be biased with respect to the load or grounded.

The EHT Switching Power Amplifier (SPA) is a IGBT or SiC MOSFET-based full bridge designed to drive resisitive, inductive, and resonant loads. The EHT SPA includes independent, fiber-optically isolated gates for each leg of the full bridge allowing the user to control which bridge legs are in forward conduction vs freewheeling.

The EHT Pulse Amplifier offers a simple way to generate high voltage pulses up to 800 V. This unit includes four independently triggered channels and features a dual voltage isolated internal supply that can rapidly actuate valves, and then hold them open continuously. 

Using our core IGBT-based switching technology, Eagle Harbor Technologies develops unique power supplies for complicated applications. Custom supplies typically include fiber optic gate control, high voltage isolation, and precision timing. The waveform generated is specified by the customer and intended for a given application.

The Eagle Harbor Technologies (EHT) Charge / Dump Control is a standardized system that automates the charging, dumping, and grounding of high voltage systems. It can be operated in both local and remote mode.

The Eagle Harbor Technologies (EHT) Rapid Capacitor Charger was designed for a specific customer application to charge quickly up to 4 nF capacitors in 100 – 300 ns (depending on capacitance).

Using our core IGBT-based switching technology, EHT custom power supplies feature fibre optic gate control, high voltage isolation, and precision timing. They can generate a customer specified waveform, specific to your application.

EHT inductive adders allow high voltage pulses into 50 Ohm loads with rise times on the nanosecond-scale. All drive components are ground-referenced. This eliminates switching jitter problems, and floating gate drive complexities. Agility of pw (pulse width) and prf (pulse repetition frequency). The output pulses are defined by input pulses to gates.

EHT has developed a solution for driving a 40 kA current yet maintaining a flat top for 10 ms in an electromagnetic coil. In order to minimize the ripple on the coil, the circuit pulse width modulates at 100 kHz. Each integrated power module (IPM) was tested at 2.5 kA/IPM.
