    Abstract: An integrated magnetic device for low harmonics three-phase front-end (1) comprising three magnetic sub-assemblies (30), wherein each magnetic sub-assembly (30) comprises a magnetic core without air-gaps, three or more wound limbs and at least five windings, three current inputs connectable to a three-phase power grid (100), at least nine current outputs, three for each current inputs, said current outputs being galvanically connected to said three current inputs and connectable to a load (200). The integrated magnetic device is designed for a low harmonics three-phase bidirectional front-end and also for AC/DC rectifier and DC/AC power inverters. Its use enables reduction of the harmonics of the currents absorbed or injected to three-phase power line by using only one device which integrates a splitter and an inductor function. Compared to known solutions, cost, material and dimensions of the integrated magnetic device are reduced.

  • Patent number: 8549731
    Abstract: Ceramic inductors are made from stacked sheets of co-fired ceramic. At least one of the ceramic sheets has a slot with a conductor disposed in the slot. The conductor has a thickness equal to a thickness of the ceramic sheet containing the slot. The conductor has a large thickness (compared to prior art co-fired ceramic inductors) and therefore can carry large currents. The present ceramic inductor can be used in power electronics applications due to the ability to carry large currents. The present ceramic inductor preferably has an inductance that decreases with increasing current. A decreasing inductance characteristic tends to increase energy efficiency in a voltage regulator when the inductor is used as an output inductor. Specifically, the variable inductance tends to substantially increase energy efficiency at low current loads without adversely affecting efficiency at high loads.

    Abstract: An adjustable EMI suppression core has an outer core having a first reluctance. The outer core has three apertures aligned horizontally. A first aperture and a third aperture are each suitable for a wire to be placed therein. A second aperture is located between the first and third apertures. An inner core is rotatable engaged in the second aperture, for example, using matching threads on an inner surface of the second aperture and an outer surface on the inner core. The inner core has first and third portions having a second reluctance similar to the first reluctance and a third portion having a reluctance considerably higher than the first and second reluctances. Rotating the inner core varies a normal mode and a common mode suppression of currents in the wires placed in the first and second apertures.

  • Patent number: 8510932
    Abstract: A method for manufacture of a conductor assembly. The assembly is of the type which, when conducting current, generates a magnetic field or in which, in the presence of a changing magnetic field, a voltage is induced. In an example embodiment one or more first coil rows are formed. The assembly has multiple coil rows about an axis with outer coil rows formed about inner coil rows. A determination is made of deviations from specifications associated with the formed one or more first coil rows. One or more deviations correspond to a magnitude of a multipole field component which departs from a field specification. Based on the deviations, one or more wiring patterns are generated for one or more second coil rows to be formed about the one or more first coil rows. The one or more second coil rows are formed in the assembly. The magnitude of each multipole field component that departs from the field specification is offset.
