Abstract
A power management apparatuscomprises: a plurality of energy harvesting input channels-; a first energy storage element connection for connecting to an energy storage element; an inductor connection; and a switching circuit. A controlleroperates the switching circuit to transfer energy between the energy harvesting input channels-and the first energy storage element connectionby a sequence of energy transfer cycles. Each energy harvesting input channel-is allocated a plurality of the energy transfer cycles. The controllerdetermines operating parameters for operating the switching circuitwhich transfer a maximum power from the electrical energy harvesting source connected to the energy harvesting input channel and a maximum power inductor utilisation factor. The controllerdetermines a set of adjusted operating parameters for sharing use of the inductor between the plurality of energy harvesting input channels-. An energy harvesting input channel-is selected for adjustment based on an effect of a change in the inductor utilisation factor and a corresponding change in power of the energy harvesting input channel.
