Our Mission

To design and deliver precision pulsed-power systems that unlock new capabilities for our customers.


Our Vision

EHT designs and builds solid-state pulsed-power systems in the USA that redefines the standard for precision pulse control. Our expertise in solid-state switching is reflected in our high-frequency pulsed-power systems that operate with nanosecond-scale precision.

At EHT, we believe that producing high-quality pulsed-power products that deliver precise and controllable pulses requires:

  • Scientists and engineers who understand the fundamental physics of solid-state switching as well as the complexity of our customers’ loads
  • Tight integration of teams developing software, control hardware, and high voltage components.
  • Continuity through the design, built, test, and delivery process
  • A dynamic and diverse team that is dedicated to learning and delivering high-quality products

Our Story

EHT was founded in 2005 to develop innovative solutions to challenges in plasma science and pulsed power. Initially, EHT’s research and product development was supported by Small Business Innovation Research (SBIR) grants from the U.S. Department of Energy (DOE), the National Aeronautics and Space Agency (NASA), and the Department of Defense (DOD). These grants allowed us to develop new capabilities in solid-state switching and plasma control. We deployed initial products based on this research to fusion energy labs at universities and national labs.

Today, EHT’s primary focus is delivering robust pulsed-power systems to our customers, enabling them to be leaders in their industries. In parallel, EHT continues to conduct SBIR-supported research and development to stay at the forefront of solid-state pulsed power.

Our Advanced Facilities

EHT is located in downtown Seattle in a facility that has 9,300 sq. ft. of space that includes offices, electronics assembly, machining, inventory, high-voltage testing, and ultra-high-vacuum testing areas.

Our laboratory area has high-voltage testing facilities equipped with high-voltage and high-power supplies and the necessary safety interlocks. These facilities also include a 30 kW chiller for water cooling. Diagnostics and data acquisition include a variety of state-of-the-art oscilloscopes and probes allowing measurement of signals up to 2 GHz and 100 kV.

Our machining, electronics assembly, and low-voltage testing areas are equipped with all the necessary equipment such as soldering stations, power supplies, and function generators to allow engineers and scientists to rapidly design, prototype, assemble, and test a wide variety of circuits.
