1. A power management system comprising:

  • a power converter for converting a thermally generated voltage, wherein the power converter comprises a low-voltage direct current to direct current voltage converter (DC-DC converter), and a high-efficiency DC-DC converter coupled with the low-voltage DC-DC converter;

    a charge storage circuit coupled with the low-voltage DC-DC converter and the high-efficiency DC-DC converter for storing converted electrical energy; and

    a programmable controller circuit coupled with the high-efficiency DC-DC converter, the low-voltage DC-DC converter, and the charge storage circuit, wherein the controller circuit substantially controls operation of the power management system when a voltage potential of the converted electrical energy stored by the charge storage circuit is greater than a first threshold value.
