Abstract : The liquid metal plasma valve (LMPV) is a high average power mercury vacuum-arc switching device. It has been extensively developed over the past ten years as a converter valve for use by the electric utilities industry at nominal average power levels of 90 MW. This paper will describe an LMPV closing switch now under development for operation in conjunction with a PFN to deliver 1 MW average power to a load in 20 to 50 (mu) sec pulses at up to 100 kV. The objective of this development is to obtain information for the de sign of switches capable of operating at much higher power levels.
