Abstract
This paper presents an inductorless triple-output
thermoelectric energy harvesting (EH) system based on a recon-
figurable thermoelectric generator (TEG) array. The TEG array
in the proposed system can be dynamically reconfigured to
achieve maximum power point tracking (MPPT) and voltage
conversion (VC) for three outputs. Two regulated outputs and
an energy recycling mechanism that can store excessive energy
in the battery and supplement insufficient energy to the load are
provided. An optimization
