Abstract (en)
[origin: EP2833378A1] The present invention is concerned with the field of power electronics, such as an induction electric apparatus, in particular a medium frequency transformer 1. The transformer 1, at least comprises a core 2, a primary winding 3, a secondary winding 4, at least one cooling channel 5, and an enclosure 6, wherein the enclosure 6 accommodates the core 2, the primary winding 3, the secondary winding 4, and the cooling channel 5 and the enclosure 6 is filled with an insulating medium 7. The least one cooling channel 5 is provided for cooling of the primary winding 3, the secondary winding 4, the enclosure 6 and/or the insulating medium 7. An insulating element 8 is placed between the primary winding 3 and the secondary winding 4, wherein a first conducting shield 9 is placed between the insulating element 8 and the primary winding 3 and a second conducting shield 10 is placed between the insulating element 8 and the secondary winding 4. Further the first conducting shield 9 is electrically connected to the primary winding 3 and the second conducting shield 10 is electrically connected to the secondary winding. The first cooling channel 5 is placed between the first conducting shield 8 and the primary winding 3.
