The invention relates to an improved method for inductive energy transmission between a primary part (I) and a secondary part (II), wherein a primary current (i s ) is introduced into a transmitting coil (L 1 ) arranged on the primary part (I) in order to create a first magnetic field which induces an electrical AC voltage (u i ) in a receiving coil (L 2 ) arranged on the secondary part (II), which electrical AC voltage causes an electrical secondary current (i v ) at the secondary part (II) and thus a power flow to at least one load (V) connected to the receiving coil (L 2 ), which power flow comprises an uncompensated active power (P N ). According to the invention, a compensation unit (K) introduces a compensation current (i K ) into a secondary-side coil (L K ), which compensation current generates a second magnetic field which is superimposed on the first magnetic field and induces a compensation voltage (u K ) in the transmitting coil (L 1 ). The compensation voltage (u K ) changes the phase shift between the primary voltage (u L1 ) that drops across the transmitting coil (L 1 ) and the primary current (i s ) that flows through the transmitting coil (L 1 ) in such a way that the transmitted active power (P R ) increases.
