Abstract
Implantable medical device systems of the present disclosure may include a subcutaneous implantable cardioverter defibrillator (SICD) that is powered by a multi-cell power source that is connected to a transformer and power conversion circuitry to charge one or more relatively small, but powerful, high voltage capacitors to provide a relatively high discharge voltage. The SICD includes electrical isolation for the multi-cell power source to protect against cross-charging between the cells during the operational lifetime of the SICD.
