1. An inductive power pad (100), comprising:

  • at least one transmitting inductor (120) operable to provide inductive energy (110) to a power receiver circuit (150); and

    a respective at least one detector circuit (140, 148) coupled to a corresponding transmitting inductor, (120) each detector circuit (140, 148) operable to electromagnetically sense a power receiver circuit (150);

    wherein each of the at least one detector circuit (140), upon electromagnetically sensing a power receiver circuit (150), is operable to control switching of its corresponding transmitting inductor (120) to a power supply (130), thereby coupling a supply voltage (160) to said corresponding transmitting inductor (120), said supply voltage (160) operable to generating inductive energy (110) for transmission to said power receiver circuit (150).
