Assignee: INFINEON TECHNOLOGIES AUSTRIA AG
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An apparatus comprising:
a main battery source operative to produce a main battery voltage;
a set of one or more auxiliary battery sources, each of which is operative to produce a respective auxiliary battery voltage; and
a controller operative to:
i) initially set a battery supply voltage to the main battery voltage, the battery supply voltage supplied to a power converter;
ii) monitor a magnitude of the battery supply voltage; and
iii) via at least one of the auxiliary battery sources in the set, adjust the battery supply voltage supplied to the power converter based on a comparison of the magnitude of the battery supply voltage with respect to a threshold level;
wherein the power converter is operative to convert the battery supply voltage into a supplemental voltage in which a summation of the supplemental voltage and the battery supply voltage produces an output voltage to power a load;
the apparatus further comprising: an energy storage resource disposed in series with the main battery source, the energy storage resource operative to store the supplemental voltage; and
wherein the controller is operative to generate the output voltage in response to detecting that an input voltage source discontinues powering the load.
