Cold cathode switching device and converter

Patent ·
OSTI ID:1632637
A cold-cathode switching device is presented. The cold-cathode switching device includes a housing defining a chamber; an ionizable gas disposed in the chamber; and a plurality of electrodes disposed in the chamber. The plurality of electrodes includes a cathode and an anode defining a discharge gap, and wherein at least one of the cathode and anode comprises a material that is liquid at an operating temperature of the cathode or the anode.
