Abstract

Official abstract text for this publication.

The invention relates to a power transformer with electronic components. The aim of the invention is to arrange the energy supply of the electronic components of a power transformer closer to the components and thus eliminate the disadvantages of the prior art. According to the invention, a stray field collector is brought into a stray field of the power transformer, whereby a voltage is generated.

First claim

Opening claim text (preview).

The invention claimed is: 1. A power transformer comprising: electronic components, a yoke having a leg; a winding surrounding the leg and generating a stray field on energization of the transformer; and a stray field collector for supplying voltage to the electronic components and including a magnetic core and a coil around the core, outside the yoke and the winding, in the stray field of the transformer, and positioned such that current is induced by the stray field in the c…
