The present disclosure concerns a method of manufacturing an electronic device, where the electronic device includes at least one electronic component with at least one electrical winding, and at least one heat dissipation mass coating, and the method includes inserting the at least one electronic component into a cavity; pouring, before or after the insertion of the electronic component, a heat dissipation mass into the cavity so as to at least partially fill the cavity and at least partially cover the electronic component with the heat dissipation mass; removing the electronic device, namely, the electronic component covered by the heat dissipation mass coating, from the cavity. The present disclosure also concerns an electronic apparatus including at least one electronic device manufactured by the foregoing method.

Electronic apparatus and method of manufacturing electronic device

An integrated magnetic component comprises a common mode inductance and a differential mode inductance. The common mode inductance is formed by a common mode core surrounding a winding window and at least two windings wound around the common mode core and through the winding window. The differential mode inductance is formed by the at least two windings and a differential mode core being spaced from the common mode core by a gap. The differential mode core comprises at least one surface being adjacent to each of the at least two windings. Further, a filter for attenuating electromagnetic interference comprises an integrated magnetic component according to the invention. Even further, the integrated magnetic component according to the invention is used for attenuating electromagnetic interference, preferably in a vehicle, a data center, or a telecommunication unit. A method for manufacturing an integrated magnetic component according to the invention comprises two steps. One step comprises providing a common mode inductance formed by a common mode core surrounding a winding window, and at least two windings wound around the core and through the winding window. Another step comprises providing a differential mode core and spacing it from the common mode core by a gap, such that at least one surface of the differential mode core is adjacent to each of the least two windings.

The invention related to an integrated magnetic component for a switched mode power converter. The integrated magnetic component comprises a single magnetic core structure formed by magnetic core elements, wherein at least one of the magnetic core elements is a leg-core-element with a flange and one or more legs are arranged on one side of the flange. The magnetic core elements of the single magnetic core structure are linearly stacked.

Herein the higher current transformer winding and the filter winding comprise at least an edgewise wound winding part. The invention further relates to a switched mode power converter.

Integrated magnetic component and switched mode power converter

The invention relates to an integrated magnetic component for a switched mode power converter, which includes a transformer with two transformer core elements (E, E) and at least one choke core element (E, E). Each core element (E, E, E, E) comprises two outer legs () and a flange () which connects the outer legs () to form U-like core elements. Each choke core element (E, E) abuts a flange () of one of the transformer core elements (E, E). The integrated magnetic component () includes a first choke winding () arranged on a leg () of a choke core element (E) and a second choke winding () arranged on another leg () of a choke core element (E), where one of a primary (P, P) or a secondary winding (S, S) of the transformer is connected between the choke windings () and where all windings (P, P, S, S) are interconnected to reduce core losses by flux compensation in order to increase power density.
