Abstract: The invention relates to a device which comprises a circuit arrangement and at least one inductive element. In order to form a device with a circuit arrangement with one or more inductive elements which can be manufactured as economically as possible, it is proposed to use an electrically conductive plate ( 13 ) having an inductive function, the inductive function corresponding to a structure of slits ( 20 a, 20 b, 20 c) formed in the plate.

Abstract: Resonant gate driver circuits provide for an efficient switching of, for example, a MOSFET. However, often an operation of the resonant gate driver circuit does not allow for an application where high switching frequencies are required. According to the present invention, a pre-charging of the inductor of the resonant gate drive circuit is performed. This allows for a highly energy efficient and fast operation of the MOSFET.

Abstract: The invention relates to a DC/DC down converter which includes a synchronous rectifier (S), a switching element (C)at its input side and an inductance (L) at its output side. In order to permit fast load fluctuations as well as to reduce costs and operating losses, it is proposed to provide an auxiliary circuit which comprises an auxiliary switching element (A), an auxiliary rectifier (Daux) and an auxiliary inductance (Laux), the auxiliary circuit being coupled to the connection between the synchronous rectifier, the switching element at the input side and the inductance at the output side.
