Description
Summary:In this paper, we design a DC/DC converter with maximum power point tracking (MPPT) function for harvesting maximum output energy from the automotive exhaust thermoelectric generator (AETEG) regardless of the engine operating conditions and values of the connected electrical load. Our developed AETEG has a multi-section structure. Due to non-uniform temperature distribution over the surface of the AETEG each section has its own temperature difference. Application of MPPT devices for such types of thermoelectric generators is accompanied by certain difficulties. Different thermal conditions of each section may cause effectivity losses of MPPT device application. Experiments are conducted with a real car engine and AETEG in order to identify the most suitable connection type between AETEG sections and MPPT device.
