| description | Energy harvesting has become increasingly important nowadays. This solution
allows the development of autonomous devices, avoiding the use of batteries, that
do not have a large duration and can be harmful to the environment.
Some energy harvesters provide very low voltages, that are therefore unable
to supply what is required by some electronic devices. This can be solved with
the use of step-up voltage converters.
Moreover, some of these are not able to provide enough power for continuously
supply to sensor nodes. With the help of a voltage monitor we can ensure that
the power is only transferred to the sensor node whenever the capacitor storing
the energy provided by the harvester is charged enough.
In this work, a Power Management Unit (PMU) for a long-range harvesterassisted wireless sensor node is proposed. The PMU is able to adapt the output
voltage of the harvester to the required voltage for the sensor node, and store its
energy in a capacitor. It also ensures that power transmission only occurs when
the capacitor is charged enough. |
