Abstract

See full text

A power management apparatus 20 comprises a first energy harvesting input channel 21; a first energy storage element connection 25; an inductor connection 27; and a switching circuit 28. A controller 30 is configured to operate the switching circuit 28 to transfer energy between the first energy harvesting input channel 21 and the first energy storage element connection 25 by a sequence of energy transfer cycles. Each of the energy transfer cycles comprises an energise phase in which energy is transferred from the first energy harvesting input channel 21 to the inductor connection 25 for an energise time (tE) and a de-energise phase. The first energy harvesting input channel 21 is capable of receiving an AC electrical signal and a DC electrical signal. The controller 30 is configured to determine a type of an electrical signal received at the first energy harvesting input channel 21, where the type is one of an AC electrical signal and a DC electrical signal, and determine an energise time (tE) and a harvesting cycle period (tP) for the switching circuit 28 based on the determined type.
