The paper presents a new method for the high-voltage glow discharge (HVGD) generation based on using a discharge system involving an electric-arc grid plasma cathode and characterized by self-sustaining combustion caused by evaporation of the collector material. The HVGD electric power supply is provided from a single source and is a combination of two different mechanisms of the current flow: the arc-current flow associated with the cathode material evaporation by the arc-discharge cathode spot, and glow flow associated with evaporation of the HVGD anode material (collector), vapor ionization, and ion-electron emission from the grid plasma cathode electrodes. Keywords: high-voltage glow discharge, arc discharge, cathode spot, grid plasma cathode, electron beam, anode plasma, vaporization of materials.
