摘要： A power bus bar assembly comprising planar electromagnetic interference (EMI) inductors. An exemplary power bus bar assembly or planar inductor comprises upper and lower E-E magnetic cores, and upper and lower flat bus bars that are insulated from each other. The bus bars have a plurality of core cut-outs that allow the cores to pass through them. The core cut-outs form an electrical path through the E-E cores that forms a turn that provides a predetermined amount of inductance. The bus bars may be arranged to form turns in the same direction or opposing directions that provide for a common mode and differential mode inductors, respectively. Different core materials and stacking of multiple cores may be used to improve the frequency response of the inductor.
