Embodiment Construction

[0030] The coil mechanism according to the invention is preferably used in an electronic control unit, preferably in a voltage regulation circuit. Preferably, the coil mechanism is used to provide a ferrite-based supply voltage (point of load or voltage regulator module) for small power ranges. This results in material savings and a high adjustment bandwidth.

[0031] According to figure 1 In a preferred embodiment, the coil mechanism 1 is integrated in the voltage regulator 5 (voltage regulation circuit). The coil mechanism 1 has a ring core. The voltage regulator 5 can realize the DC voltage U applied to the first capacitor C1 dc reduced to a lower voltage U applied across capacitor C2 on the output side b superior. For example the output voltage can be U b = 2 volts. Since the iron-based alloy is able to withstand significantly increased loads, in a further preferred embodiment significantly increased power is transmitted. Accordingly, the output voltage can be, for...

Abstract

The invention relates to a converter device comprising a converter and a coil arrangement that contains a number of coils, wherein the coil arrangement has a plurality of interconnected coils, and toroidal cores consisting of a soft magnetic nanocrystalline material are associated with each of said coils, a coupling toroidal core (11) being provided with a core opening (12) through which at leasttwo windings (8, 9) of different coils can be guided and mounted, at least the winding of one coil being guided and mounted through a core opening of an individual toroidal core (13, 14), and an open / closed-loop control device being provided with a current controller that acts on the coils such that direct current components are compensated by currents flowing through the windings of the coils.

Description

technical field [0001] The invention relates to a converter device having a converter and a coil arrangement comprising a certain number of coils. Background technique [0002] From DE 10 2012 206 225 A1 a coil with a low-permeability annular band core consisting of a nanocrystalline soft magnetic material is known. The windings of the coil are led through the core opening of the annular strip core. In order to improve the properties of the coil and in particular to reduce the volume of the coil, it is known that the annular strip core of the coil has regions with different magnetic permeability. The endless belt core is constructed such that the magnetic permeability increases radially outward. However, the improved properties of the known coils are traded at increased manufacturing costs, since the coils consist of core rings of different materials. [0003] A production method for a nanocrystalline annular belt core is known from DE 10161907 A1. [0004] An isolating ...
