ELECTRICAL TRANSFORMER WITH RESONANT PRIMARY AND INDUCTIVE SECONDARY AND ITS MANUFACTURING METHOD

Abstract: an electric transformer with a resonant primary and an inductive secondary includes a magnetic core, a primary winding having a first polarity and a secondary winding comprising a bifilar winding coupled in parallel to the primary winding and having an opposite polarity to the first polarity, the bifilar winding comprising a first winding and a second winding interconnected in series at a central derivation point, to which a first end of the capacitor is connected, the second end of the capacitor being connected to the input of the primary winding, wherein the first winding and the second winding each comprises a number of turns that corresponds to 40% of the number of turns of the primary winding; and wherein the bifilar winding is arranged in the same leg of the magnetic core of the primary winding. and a method for manufacturing the electric transformer.
