Abstract
An energy harvesting system for transferring energy from an energy harvester () having an output impedance (Z) to a DC-DC converter () includes a maximum power point tracking (MPPT) circuit () including a replica impedance (Z) which is a multiple (N) of the output impedance. The MPPT circuit applies a voltage across the replica impedance that is equal to an output voltage (V) of the harvester to generate a feedback current (I) which is equal to an input current (I) received from the harvester, divided by the multiple (N), to provide maximum power point tracking between the harvester and the converter.
