Abstract
An electrical inductor assembly has a plurality of three-phase inductors on a common core. Each inductor includes three coils wound around separate legs of the core. Core bridges extend across the legs to provide an inter-leg path for the magnetic flux produced by each coil. The magnetic flux from all the coils of adjacent inductors flows through a common core bridge in a manner wherein the magnetic flux in the common core bridge is less than the sum of the magnetic fluxes in each leg.
