1. A wireless power receiver, the receiver having a secondary inductor to receive power via an inductive coupling with an independent power supply, the receiver having a rectifier, in circuit with a current modulator responsive to a controller to superimpose a pulsed current signal for inductive communication with an inductively coupled power supply;

  • wherein the current modulator is adapted to shape the signal current pulse in such a way that after circuit distortion, the communication pulse shape seen by the secondary inductor more closely resembles an ideal rectangular step function.
