摘要： An apparatus for transmitting electrical energy to an electrical consumer, includes a transmitter device for transmitting an electrical energy having at least one first coil and a first capacitor for producing a resonant tank circuit at the transmitter device; at least one receiver device for receiving the energy transmitted by the transmitter device, including a second coil and a capacitor for producing a resonant tank circuit at the receiver device, wherein the receiver device is connectable to the consumer to form an electrical connection; a power amplifier; a transformer for matching the impedance between the resonant tank circuit at the receiver device and the consumer; and an electrical energy source—for supplying the resonant tank circuit at the transmitter device with electrical energy. The transmitter device and the receiver device jointly form a resonant tank circuit for transferring the electrical energy from the transmitter device to the receiver device, such that at the receiver device the electrical energy made available by the transmitter device can be fed to the consumer.
