1. An apparatus adapted to transmit wireless energy from an external energy transmitting device placed externally to a human body to an internal energy receiver placed internally in the human body, the apparatus comprising, a first electric circuit to supply electrical pulses to the external transmitting device, said electrical pulses having leading and trailing edges, said external transmitting device adapted to transmit wireless energy placed externally to a human body to an internal energy receiver placed internally in the human body, whereinthe first electrical circuit being adapted to vary the lengths of first time intervals between successive leading and trailing edges of the electrical pulses and/or the lengths ofsecond time intervals between successive trailing and leading edges of the electrical pulses, and whereinthe transmitted wireless energy, generated from the electrical pulses having a varied power, the power depending on the lengths of the first and/or second time intervals, wherein
the first electric circuit has a time constant, and
the first electric circuit is adapted to provide the electrical pulses varying the first and second time intervals to have lengths in the range of, that are in the magnitude of order of or are shorter than, the first time constant, and a relationship or proportion between the lengths of the first and second time intervals is varied, whereby, by the varying a varying power is transmitted.
