The methodology presented in this paper allows to increase the thermoelectric figure of merit by modulating either the input voltage or the input temperature difference, depending on the operation mode. This is possible through two different transfer equations, determined in this document by means of the theory of thermoelectric complete response, one for thermoelectric generator and the other one for thermoelectric cooler. Both equations were modified including the duty cycle, allowing it to boost the thermoelectric figure of merit to 1.325. The experiments carried out for testing and verification of this method considered a thermoelectric module based on bismuth telluride material, non-ideal contacts, and non-adiabatic conditions at room temperature, i.e., 300K.
