Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A high voltage driving device comprising:
a housing; and
a first electrode, a second electrode, and an insulation structure, which are disposed in the housing,
wherein the first electrode and the second electrode are spaced apart from each other with the insulation structure therebetween,
wherein the insulation structure comprises:
a pair of first solid insulators respectively disposed adjacent to the first electrode and the second electrode; and
a second solid insulator disposed between the first solid insulators,
wherein the first solid insulator has first volumetric resistivity or first permittivity less than second volumetric resistivity or second permittivity of the second solid insulator, the first volumetric resistivity being sufficiently small to suppress a charging phenomenon on a surface of each of the first solid insulator, and
wherein the first solid insulators respectively contact the first electrode and the second electrode.
