Patent ID: 8884466

Claim:
A high voltage power supply (HVPS) comprising: a substrate having a first direction, the substrate having an upper area comprising a first edge portion and a lower area comprising a second edge portion with respect to the first direction; a first high voltage output controller disposed on the upper area of the substrate; a first plurality of transformers disposed on the upper area of the substrate to transform output signals of the first high voltage output controller as first transformed signals, the first plurality of transformers comprising first primary input terminals to receive output signals of the first high voltage output controller and first secondary output terminals to output the first transformed signals; a first plurality of edge output terminals disposed on the first edge portion, to be connected to the first secondary output terminals; a second high voltage output controller disposed on the lower area of the substrate; a second plurality of transformers disposed on the lower area of the substrate to transform output signals of the second high voltage output controller as second transformed signals, the second plurality of transformers comprising second primary input terminals to receive output signals of the second high voltage output controller and second secondary output terminals to output the second transformed signals; and a second plurality of edge output terminals to be connected to the second secondary output terminals, wherein the first high voltage output controller is disposed closer to the first primary input terminals than the first secondary output terminals and controls the first plurality of transformers, the second high voltage output controller controls the second plurality of transformers, and the first secondary output terminals are disposed closer to the first edge portion than the first primary input terminals.
