Abstract

Methods and systems for increasing capacitor reformation efficiency in an implantable cardiac device (ICD) are presented. In one embodiment, a method and system provide for: (1) fully charging a first capacitor, (2) transferring energy from the first capacitor to an inductor, (3) transferring energy from the inductor to the second capacitor, and (4) completing charging of the second capacitor. In another embodiment, a method and system provide for: (1) fully charging a first capacitor, (2) sharing energy from the first capacitor with a second capacitor, and (3) completing charging of the second capacitor. In yet another embodiment, a method and system provide for: (1) fully charging a first capacitor, (2) sharing energy from the first capacitor with a second capacitor, (3) transferring remaining energy from the first capacitor to an inductor, (4) transferring energy from the inductor to the second capacitor, and (5) completing charging of the second capacitor.
