In the present investigation, the application of the modified Johnson converter on a thermoelectric module is described. The electrical voltage and current are the thermoelectric module’s input, and output is the temperature difference between two surfaces. If the reverse voltage is applied to the thermoelectric module, the temperature of the surfaces is also reversed. The modified Johnson converter acts as a power conditioning block between the power source and thermoelectric module. The required operating voltage and current for the thermoelectric module can be obtained by modulating the duty ratio. A temperature gradient is developed for a duty ratio between 0 and 0.5. However, this temperature gradient is negative for the duty ratio between 0.5 and 1. Modeling the thermoelectric module LIARD ETX4-12-F1-4040-TA-RT-W6 is done through mathematical equations. A detailed simulation study is done for heating and cooling applications, and some important results are presented.
