Implementation of a P&O MPPT algorithm in low-milliwatt-scale energy harvesting wireless sensor nodes

Abstract:

The Fractional Open-Circuit Voltage (FOCV) based Maximum Power Point Tracking (MPPT) method, typically used in low power energy harvesting circuits, is not truly dynamic and wastes harvestable energy in each MPPT cycle. Commercial-off-the-shelf (COTS) energy harvesting chips offer provision for externally setting the MPPT reference using more accurate and dynamic algorithms like Perturb-and-Observe (P&O), Incremental Conductance (INC) etc., but this can come at the cost of increased power con...
