Abstract

Fast and repetitive switching in high-power circuits is a challenging task where the ultimate solutions still have to be found. Areas of application are pulsed power technology and power stations. We proposed a new approach. Supercritical fluids have insulation strength and thermal properties like liquids and fluidity, self-healing and absence of bubbles like gases. That's why we start investigating the subject of plasma switches in supercritical media. First results indicate excellent switch recovery and high insulation strength.
