1. An implantable medical device, comprising:

  • a coil for receiving a magnetic charging field from an external charger, the magnetic charging field inducing an AC voltage in the coil;

    a rectifier for producing a first DC voltage from the AC voltage;

    a converter for producing a second DC voltage from the first DC voltage, wherein the second DC voltage is higher than the first DC voltage, and wherein the converter is adjustable to adjust the magnitude of the second DC voltage; and

    a battery, wherein the second DC voltage provides power to charge the battery.
