High Voltage and Power Plasma Switches

High Voltage and High Coulomb Pseudo Spark Switch

reference paper [10] reference paper [11]

It is difficult to find a high voltage and high coulomb transfer switch.
We had worked on pseudo-spark switches to mainly develop high coulomb transfer devices.
The preliminary data showed ~20 kV, ~100 kA, and 75 coulomb operating performance.
