The invention relates to an apparatus with a device for simultaneous transfer of electrical power and information between two components being movable to each other and preferably comprising a stationary and a movable component. According to the invention the apparatus includes a transfer device for the common transfer of power and information, with a primary coil arrangement (5, 6) mounted on one of the components and a secondary coil arrangement (11) mounted on the other component, a power supply (35, 41, 59) connected to the primary coil arrangement (5, 6) and based on pulse width modulation, and means (71, 72) for modifying signals generated by the power supply in dependence on the information to be transferred. The information can be transferred both from the one component to the other component and vice versa (FIG. 6).
Apparatus having a first component (16), a second component (18), both components (16, 18) being movable relative to each other, and a device for simultaneous transfer of electric power and information between said components (16, 18) through contact-free, inductive coupling, wherein said device comprises a common transfer means for transfer of the power and the information and having a primary coil arrangement (1) mounted on said first component (16) and a secondary coil arrangement (2, 27) mounted on said second component (18), a power supply being connected to said primary coil arrangement (1, 24), being based on pulse width modulation and being operated at a predetermined clock frequency and with a predetermined duty cycle, and modifying means (71, 72 or 10, 115 to 119) for modifying of signals generated by said power supply in dependence of said information to be transferred.
