Classification: CPC H | IPC H

Claim 0:
1. A high voltage driving device comprising:
a housing; and
a cathode, an anode, and an insulation structure, which are disposed in the housing,
wherein the cathode and the anode are spaced apart from each other with the insulation structure therebetween,
wherein the insulation structure comprises:
a first solid insulator disposed adjacent to the cathode; and
a second solid insulator disposed adjacent to the anode,

wherein the first solid insulator has first volumetric resistivity less than second volumetric resistivity of the second solid insulator, the first volumetric resistivity being sufficiently small to suppress a charging phenomenon on a surface of the first solid insulator, and the first solid insulator contacts the cathode.
