Abstract: A magnetic core is provided. The magnetic core includes a plurality of magnetic core units each having at least one non-shared magnetic core part that is not shared with the neighboring magnetic core unit, wherein a reluctance of the shared magnetic core part is smaller than the reluctance of a non-shared magnetic core part of the magnetic core units, and directions of a direct current magnetic flux in the shared magnetic core part of the neighboring two magnetic core units are opposite.

Abstract: A radio frequency interference suppression circuit that includes a reference ground end, a main power circuit, a driving circuit and an impedance unit is provided. The main power circuit includes a first switch that includes a control end, a first and a second end. A minimal impedance is presented between the second end and the reference ground end. The driving circuit is coupled to the control end and the second end. The first impedance unit is formed between the second end and the reference ground end in a high frequency differential mode loop to reduce a high frequency voltage drop therein. The first switch receives a driving signal from the driving circuit to be turned on or turned off between the first and the second ends accordingly to make the main power circuit converts a first power signal to a second power signal.

Abstract: An integrated inductor apparatus integrated to be a plurality of inductors is provided. The integrated inductor apparatus includes inductor windings to form inductors and includes at least two windows each having at least one of the inductor windings disposed therein and magnetic core units, each having a closed geometrical structure to form one of the at least two windows, wherein two of the neighboring magnetic core units have a shared magnetic core part. The magnetic core units comprise at least two kinds of material having different magnetic permeability corresponding to different sections of the magnetic core units, wherein the reluctance of the shared magnetic core part is smaller than the reluctance of a non-shared magnetic core part of the magnetic core units.
