1. A power system, comprising:
- a sensor;
an energy harvesting device operable to deliver power to the sensor;
a battery coupled to the energy harvesting device and the sensor; and
a circuit coupled to the energy harvesting device and the battery, the circuit adapted to control delivery of power to the sensor by providing power generated by the energy harvesting device to the sensor without delivering excess power to the battery and to supplement the power generated by the energy harvesting device with power from the battery if the power generated by the energy harvesting device is insufficient to fully power the sensor.

Abstract
A power system includes an energy harvesting device, a battery coupled to the energy harvesting device, and a circuit coupled to the energy harvesting device and the battery. The circuit is adapted to deliver power to a load by providing power generated by the energy harvesting device to the load without delivering excess power to the battery and to supplement the power generated by the energy harvesting device with power from the battery if the power generated by the energy harvesting device is insufficient to fully power the load. A method of operating the power system is also provided.
