Conventional MPPT methods require a closed-loop controller and perturb and observe (P&O) method to provide fast-tracking response. However, they produce power loss due to small oscillations in the steady state. The proposed method excludes the use of closed-loop controller and steady-state oscillations by directly estimating the coordinates of MPP using three random operating points on the parabolic P–I curve. To substantiate the effectiveness of the parabolic extrapolation-based MPPT algorithm, different conditions of temperature gradient and load have been applied. The results demonstrate that the proposed algorithm takes <15% of the time taken by P&O method to track the MPP.}, title = {MPPT algorithm for thermoelectric generators based on parabolic extrapolation}, journal = {IET Generation, Transmission & Distribution}, issue = {6}, volume = {13}, year = {2019}, month = {March}, pages = {821-828(7)}, publisher ={Institution of Engineering and Technology}, copyright = {© The Institution of Engineering and Technology}, url = {https://digital-library.theiet.org/;jsessionid=dieqsqlkvsib.x-iet-live-01content/journals/10.1049/iet-gtd.2017.2007} }
