| 摘要 |
The invention relates to a primary-side coil assembly for an inductive energy transfer system for transferring energy between a primary- and a secondary-side coil assembly (A1, A2). The invention is characterised in that the primary-side coil assembly (A1) has four coils (z, SP3, SP4) which form the four adjacent coil regions (BEP1, BEP2, BEP3, BEP4) of the coil assembly (A1), the phase position (ΦIi) of the coil fluxes (SP1, SP2, SP3, SP4) in relation to one another flowing through the coils (I1, I2, I3, I4) determining the phase position (φBi) of the magnetic flux density (Bi) which is established in the regions (BEP1, BEP2, BEP3, BEP4). With the use of a secondary-side coil assembly (A2) comprising four adjacent coil regions (BEs1, Bes2, BEs3, BEs4), the phase position (ΦIi;) of the coil fluxes (I1, I2, I3, I4) is established such that in the four regions (BEP1, BEP2, BEP3, BEP4) of the primary-side coil assembly (A1), the phase position (ΦBi) of the respective magnetic flux densities (Bi) which are established is 0°, 90°, 180° and 270° in relation to one another. |
