Abstract
A radial type of high voltage solid-state switch is essentially a gated diode switch (GDS) with portions of the anode, cathode, shield, and gate regions being arc portions of concentric circles which have different radii. The arc length and radius of the arc portions of the anode are less than the corresponding parameters of the shield and cathode. This structure, which is denoted as a radial gated diode switch, RGDS, has lower on resistance than a standard GDS of the same area and distance between anode and shield regions.
