US Patent 7417522 High voltage transformer

A high voltage transformer is small-sized, lightweight and less costly to fabricate. The high voltage transformer is designed to maintain equal the potential difference between the components of two transforming component groups and also to keep the components of the respective transforming component groups equipotential at the same distance in the direction extending from a first end to a second end. This eliminates the need to dispose an insulating body between the components of the first and second transforming component groups. This also makes it possible to fabricate the high voltage transformer with a small size and in a cost-effective manner.
