This paper proposes a novel Maximum Power Point Tracking (MPPT) control method of thermoelectric power generation for the constant load. This paper reveals the characteristics and the internal resistance of thermoelectric power module (TM). To control the operating point & to extract the maximum power from waste heat using TEG is essential as there is a wastage of heat from Industries, automobiles etc. To fix maximum power point from waste heat, a good number of algorithms has been proposed, one of them is P&O algorithm. Analyzing the thermoelectric power generation system with boost chopper by P&O Method, the output voltage and current of TM are estimated by with only single current sensor. The basic principle of the proposed MPPT control method is discussed, and then confirmed by digital computer simulation using Matlab. Simulation results demonstrate that the output voltage can track the maximum power point voltage by the proposed MPPT control method. The comparative analysis between P&O and modified Perturb & Observe (P&O) algorithm for extracting the power from thermoelectric array TM is analyzed briefly below.
