Abstract
Proposed are an energy harvesting-based power supply switching device and a method thereof. An energy harvester may collect ambient energy and convert the collected energy into electric energy. An electric energy storage may store the converted electric energy. A plurality of power converters may convert the stored electric power into necessary electric power required by loads. A plurality of voltage supervisors monitor a voltage of power supplied from the power converters to the loads. A power supply switching unit switches supply of power from the power converters to the loads. A controller identifies the necessary power of the loads, then switches the supply of power by using the power supply switching unit based on an amount of the stored power and monitoring information received from the voltage supervisors, and performs power switching with one of the power switch and the ground switch according to the necessary power of the loads.
