Claim Text:
1. A high voltage transformer, the high voltage transformer comprising: a primary winding, a high voltage winding and a transformer core, wherein the primary winding and the high voltage winding encircle concentrically at least a part of the transformer core, and wherein the high voltage winding has a higher number of turns than the primary winding, and comprises one single layer or a plurality of single layers connected in parallel, wherein therebetween the primary winding and the high voltage winding is an annular opening therethrough for providing high voltage insulation distance and passage of cooling fluid, wherein the annular opening is further configured to provide a low capacitance between the primary winding and a secondary winding, and the annular opening is further configured between the primary and secondary windings and the transformer core.
