The transcutaneous power supply and/or recharger device of the present invention enables a precise centering of the device with a receiver coil in an implant. In one embodiment, the power supply device includes a plurality of satellite sensors or coils disposed around the transmitter coil. A voltage value detected in the receiver coil is transmitted to the power supply or recharger device via a telemetric channel and indicates the amount of power being transferred, and, therefore, the accuracy of the reciprocal positioning of the power supply terminal with the receiver coil.
