Abstract: A device is provided that integrates a plurality of inductors in parallel. The device includes a plurality of windings and a magnetic core structure. A number of the windings corresponds to a number of the inductors. The magnetic core structure includes a plurality of windows, wherein each window includes at least two windings coupled with each other. When a phase difference of the voltage phases is smaller than a predetermined value, voltage phases of two terminals of any two of the windings within the same window are substantially the same.

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.
