ABSTRACT:
An exemplary system for providing power to a rechargeable battery in an implantable stimulator includes a first coil configured to emit a first magnetic field, a coil in the stimulator configured to receive the first magnetic field, and a zero volt recovery (ZVR) circuit in the stimulator configured to use the first magnetic field to cause the coil in the stimulator to be tuned to a frequency of a second magnetic field. The second magnetic field is used to provide the power to recharge the battery. An exemplary method of providing power to recharge a battery in an implantable stimulator includes transmitting a first magnetic field used to provide the power to recharge the battery, transmitting a second magnetic field; and using the second magnetic field to cause a coil in the stimulator to be tuned to a frequency of the first magnetic field.
