Definitions
- the invention relates to an arrangement for an inductive energy transmission with a transmitter having at least one transmitter coil and a recipient of a receiver coil arrangement having a consumer.
- Charging station with a plurality of transmitting coils is used to charge the batteries of applied mobile phones, tablets or the like.
- Receiver-coil assembly having a receiver
- the two coils are electrically coupled, comparable to a transformer.
- Such a transformer conversion directly in the receiver coil arrangement has the advantage of being able to supply a low output voltage, so that the
- any non-conductive plastic can be used as a substrate.
- any non-conductive plastic can be used.
- conventional printed circuit boards, films or plastic housing of a consumer are suitable.
- As a coil geometry a rectangle is preferred, although other shapes are quite possible. Regardless, it is provided that the coils have congruent outer and inner edges of the outer and inner turns.
- the edges of the outer turns are as it were in a common, virtual tube and surround the inner edges of the inner turns such.
- Receiver can be formed offset from the substrate.
- the receiver coil assembly is a very flat component, only occupied with the resonance of the coil-determining components that in SMD technology
- the transmitting coil is arranged opposite in or on the consumer.
- This coil is the actual receiver coil, through which, however, a resonant circuit is connected only with a capacitor.
- the number of turns will be determined essentially by the transmission frequency. For example, the number of turns is one
- the number of turns of the second coil is significantly smaller and is determined by the height of the second coil
- the number of turns of the second coil for example, be 2 to 4.
- the power supply of the receiver in particular a microcontroller, is tapped off.
- the power supply of the receiver and the consumer are separated.
- the first coil is tuned to resonance, alternatively, that the second coil to resonance
- Fig. 2 is a plan view and Fig. 3: a bottom view of one with the
- Receiver coil assembly provided substrate.
- a transmitter 1 is shown schematically in an equivalent circuit diagram, which via a drive circuit 2, a plurality of transmitting coils 3, indicated by the arrow, individually or in groups for an inductive
- Receiver coil arrangement with a first coil 4 and a second coil 5 for the power supply of a particular mobile consumer 6.
- the first and the second coil 4,5 are applied planar on both sides of a substrate 7, as will be explained further below.
- Rectifier circuit 10 and a DC / DC converter 11 for a fine control of the supply voltage of the consumer. 6
- the second coil 5 will have significantly fewer turns than the coil 4.
- the second coil 5 has a center tap 12, from which the receiver circuit 13 is fed, here exemplified as a microcontroller 14, which a rectifier 15 and a DC / DC converter 16 is still connected upstream.
- the second coil is the fifth
- the board or the substrate 7 carries in addition to the two coils 4, 5 only the capacitors 8,9 and here, for example, a connector strip 17 for connecting the
