Abstract:
1. An integrated magnetic device for low harmonics three-phase front-end comprising three magnetic sub-assemblies, wherein each magnetic sub-assembly comprises a magnetic core without air-gaps, three or more wound limbs and at least five windings, at least one first common yoke and a second common yoke which magnetically couple said three magnetic sub-assemblies, a first air-gap between said three magnetic sub-assemblies and said at least one first common yoke, a second air-gap between said three magnetic sub-assemblies and said at least one second common yoke, three current inputs connectable to a three-phase power grid, and 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.
