Patent ID: 8103892

Claim:
A power management apparatus comprising: a first electrical lead routing electrical current at a first electrical lead electric potential level; a first electrical parameter sensor configured to measure a first electrical lead electrical parameter; a second electrical lead routing electrical current at a second electrical lead electric potential level; a second electrical parameter sensor configured to measure the second power electrical parameter; a buck boost converter electrically coupled to both the first electrical lead and the second electrical lead, the buck boost converter being configured to convert electrical current between the first electrical lead electric potential level and the second electrical lead electric potential level at a controlled potential conversion level; and a controller being configured to receive operating current from either one of the first electrical lead and the second electrical lead, the controller configured to monitor the first electrical parameter sensor and the second electrical parameter sensor and being configured to output control signals to the buck boost converter, said control signals being determined based on the first electrical lead electrical parameter and the second electrical lead electrical parameter.
