Abstract (en)
A hybrid core for a power inductor is made of at least two different soft magnetic materials which differ from each other in at least two magnetic parameters. Inductors for both single-phase and three-phase applications have superior performance with respect to targeted properties such as inductance, dc bias capability, core losses, winding losses and/or dimensions as compared to equivalent inductors made of a single magnetic material.
