The paper shows the design and implementation of a novel power management unit that combines (mixes) several power harvesting sources and delivers (routes) the power to the working load and the battery. The system can also re-utilizes the power saved in the battery during moments with high harvesting power output to complement the needed operating power of the load in case of insufficient power from the solar harvesting units.
