ELECTRONIC POWER MANAGEMENT SYSTEM FOR A WEARABLE THERMOELECTRIC GENERATOR

摘要

A power management system for an energy harvesting device configured to provide a source voltage. The power management system may include a conditioning and control circuit configured to perform an initialization process by accumulating energy from the source voltage until an output voltage becomes regulated for a load. The power management system may include a priming circuit configured to supplement the source voltage during a load period upon actuation of a power management switch which may cause the transferring of a priming charge from a low-leakage energy storage element to the conditioning and control circuit. The conditioning and control circuit may combine the priming charge with the energy accumulating from the source voltage. The initialization process may cause the output voltage for the load to become regulated during the load period following actuation of the power management switch.

1. A power management system for an energy harvesting device, comprising:
a priming circuit being associated with a conditioning and control circuit, the conditioning and control circuit being configured to accumulate energy from a source voltage until an output voltage becomes regulated for a load; the priming circuit being configured to supplement the source voltage produced by an energy harvesting device during a load period upon the actuation of a power management switch causing the transferring of a priming charge from a low-leakage energy storage element to the conditioning and control circuit; and the conditioning and control circuit combining the priming charge with the energy accumulating from the source voltage and causing the output voltage for the load to be regulated during the load period following actuation of the power management switch.
