The applications of direct current are limited in medium and high power systems because of the problems in switching. In this paper, a circuit of a multi-stage dc hybrid switch is proposed for medium-power (10kW) highly-inductive dc systems. Based on

The high-frequency fluctuations, superimposed on arc current, ion current, light intensity and arc voltage of a single cathode spot Cu-vapour vacuum discharge are investigated. For a current above approximately 40 A, fluctuations in arc current are s

Transient electron shield currents in vacuum arcs

It is shown that a conducting shield, as a third electrode in a vacuum arc plasma, can temporarily act as an auxiliary anode. This is due to an inductive shift of arc plasma potential caused by a sufficiently rapid decrease of arc current. Using curr
