Abstract

A common mode choke includes at least two groups of multi-phase coils wound on a magnetic core for balancing differential mode inductance between the phases. The multi-phase coils in each group are series connected and concentrically wound on a respective portion of the magnetic core. Each group of multi-phase coils is non-overlapping with each other group of multi-phase coils.
