Abstract

A lead frame for electrically coupling a plurality of inverter legs of an inverter to a set of coil windings of an electric motor or generator, the lead frame comprising a printed circuit board having a plurality of circuit board layers. Each circuit board layer includes an insulating substrate having an electrically conductive layer formed on the insulating substrate. First, second and third circuit board layers each include a respective electrically conductive layer arranged to be coupled to a corresponding coil winding of the first set of coil windings and a respective inverter leg. A fourth circuit board layer includes a respective electrically conductive layer arranged to be coupled to all of the third coil windings to form a neutral point therebetween.
