Resonant circuit for transmitting electric energy without a power amplifier

An apparatus for transmitting electrical energy to at least one electrical consumer, the apparatus comprising:

• at least one transmitter for transmitting an electrical energy having at least one first coil and at least one first capacitor for producing a resonant tank circuit at the transmitter;
• at least one receiver for receiving the energy transmitted by the transmitter, the receiver including at least one second coil and at least one second capacitor for producing a resonant tank circuit at the receiver, wherein the receiver is connectable to the consumer to form an electrical connection;
• a transformer for matching an impedance between the resonant tank circuit at the receiver and the consumer, the transformer including the at least one second coil of the receiver;
• and
• an electrical energy source for supplying the resonant tank circuit at the transmitter with electrical energy;
• the transmitter and the receiver jointly forming a series resonant tank circuit for transferring the electrical energy from the transmitter to the receiver, such that at the receiver the electrical energy made available by the transmitter can be fed to the consumer.
