Abstract:
An implantable medical device includes a low-power circuit and a multi-cell power source. The cells of the power source are coupled to a transformer in a parallel configuration. The transformer includes multiple secondary windings and each of the windings is coupled to a capacitor that stores energy for delivery of a therapy to a patient. In accordance with embodiments of this disclosure, the low power circuit is configured to control simultaneous delivery of energy from each of the cells to a plurality of capacitors through the transformer.
