Abstract
A transformer is configured to include a pair of cores that each have an inner leg, wherein a primary winding that is wound around a bobbin having a hollow into which the inner legs of the cores are inserted and that is hermetically sealed with resin material, and a secondary winding that has a hollow into which the inner legs of the cores are inserted and that is constituted of a conductor formed by die-cutting a metal plate into a ring are dispersedly arranged over the inner legs of the cores.
Claims12
A high-voltage and high-frequency insulation transformer comprising:
- cores that each include legs that configure a magnetic path;
- a plurality of windings that are wound and provided in the legs;
- and
- a bobbin that is formed of resin material having a low dielectric constant and high insulating properties, wherein
- from among the plurality of windings, a winding to which a high voltage is to be applied is wound around the bobbin and is hermetically sealed with insulating resin, so as to be integrally formed with the bobbin.
