A zero-sequence blocking transformer includes a first core part around which is wound a first winding and a second core part around which is wound a second winding, and a third core part to create an additional leakage flux path. The concept of this disclosure can be applied to any known core structure by adding an additional leakage flux component part. In the case of a known toroidal core, the additional component part may be a rod of magnetic material fitted into the gap between the two windings to intentionally create an additional leakage flux path. Alternatively, an EE core geometry can be used and the additional leakage flux path is created by forming an air gap or adding a magnetic material insert in the leg which does not carry a winding.

An inverter having a first busbar for connection to a positive pole of a battery and a second busbar for connection to a negative pole of the battery and a filter element that includes an annular core surrounding the first and the second busbar and made from a ferromagnetic material. It is proposed that a core made from a further ferromagnetic material to be provided in an intermediate space surrounded by the annular core and formed between the two busbars.

A multipole permanent magnet may be provided with a magnetic-field shunt. The multipole permanent magnet may be formed from compression-molded magnetic particles such as magnetically anisotropic rare-earth particles in an elastomeric polymer. The magnetic-field shunt may be formed from magnetic members in a polymer binder that are separated by gaps to allow the shunt to flex or from magnetic particles in a polymer binder. The magnetic particles in the polymer binder may be ferrite particles or other magnetic particles. The polymer binder may be formed from an elastomeric material and may be integral with the elastomeric polymer of the multipole permanent magnet or separated from the elastomeric polymer of the multipole permanent magnet by a polymer separator layer. Conductive particles may be formed in polymer such as the elastomeric polymer with the magnetic particles. The conductive particles may be configured to form electrical connector contacts and other signal paths.
