Abstract :
A new concept of maximum power point tracking control method for Thermoelectric Power Generator (TEG) systems has been developed. The virtual load conductance of the load is feedback controlled to maintain the same value of the internal conductance of the thermoelectric (TE) array using DC-DC converter. The prototype Maximum Power Point Tracker (MPPT) circuit, which is composed of buck-boost DC-DC converter, has been developed successfully. The circuit showed excellent tracking ability as MPPT against the change of load and heat source temperature as well as having wide matching ability
