<p>A method of inductively transmitting energy and information between an energy transmitter (1) comprising a primary inductor (2) and an energy receiver comprising a secondary inductor (14), wherein energy is transmitted from the energy transmitter (1) to the energy receiver by applying an alternating voltage to the primary inductor (2) to generate a primary alternating current in the primary inductor (2), thereby inducing a secondary alternating current in the secondary inductor (14). The information is transmitted from the energy transmitter (1) to the energy receiver essentially only in a dedicated first section of the cycle of the alternating voltage by varying the amplitude of the alternating voltage; and information is transmitted from the energy receiver to the energy transmitter (1) essentially only in a dedicated second section of the cycle by varying the secondary inductor's (14) power absorption, the second section not overlapping with the first section.</p> |
