Abstract
A method is provided for controlling power delivery from an external power transfer system (EPTS) to at least one implantable neurostimulator system (INS). The method comprises driving a first transmit coil within the EPTS using a transmit coil driver circuit, receiving, using a receive coil, power transferred from the first transmit coil, coupling the received power to a regulator circuit, monitoring the regulator circuit, communicating a message to the EPTS using a back telemetry circuit, receiving the message, and adjusting the transmit coil driver circuit.
