Abstract (en)
The present invention relates to a planar transformer that comprises a primary winding (201) formed on at least one primary layer (102), a secondary winding (202) formed on at least one secondary layer (104), and a compensation winding (203) formed on a compensation layer (103) that is arranged between one primary layer (102) and one secondary layer (104). The planar transformer further comprises a first conductive area (204) formed on the compensation layer (103) and connected to the compensation winding (203), and a second conductive area (205) formed on the secondary layer (104) adjacent to the compensation layer (103) and located in parallel with the first conductive area (204). The present invention also relates to a method for reducing common-mode noise in a planar transformer.
