Abstract
Embodiments presented herein are generally directed to inductive charging techniques in an implantable medical device system comprising an inductive charger and an external component. The external component includes a rechargeable battery and an inductive coil that is configured to form an inductive charging link with a charging coil in the inductive charger to receive power signals from the inductive charger. A voltage increasing converter in the external component is configured to step-up a voltage of the power signals received from the inductive charger for use in recharging the rechargeable battery.
