Abstract
A power management apparatuscomprises a first energy harvesting input channel; a first energy storage element connection; an inductor connection; and a switching circuit. A controlleris configured to operate the switching circuitto transfer energy between the first energy harvesting input channeland the first energy storage element connectionby 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 channelto the inductor connectionfor an energise time (tE) and a de-energise phase. The first energy harvesting input channelis capable of receiving an AC electrical signal and a DC electrical signal. The controlleris configured to determine a type of an electrical signal received at the first energy harvesting input channel, 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 circuitbased on the determined type.
