Comparison of Thermoelectric Generator with Boost Converter and Single-Ended Primary-Inductance Converter

Thermoelectric generator (TEG) is a clean and noiseless renewable energy source from heat source, and it can become an alternative way of generating electricity consciously. Building a thermoelectric generator converter can consist of different parts. In this research, we are studying the difference of using boost converter with single-ended primary-inductance converter (SEPIC) with the thermoelectric generator system. The contribution of the study is to determine the performance of TEG using different topology. It is done using a simulation using Matlab Simulink with varying temperature flux and load resistance. Varying the temperatures can give a consistent output, while varying load resistance by increasing can lower the performance of the thermoelectric generator system. It can also be seen that the settling time increases when the load increases. The performance of the boost converter (98.7% efficiency) is better than SEPIC (97.4% efficiency), but it is also according to the designer’s desired outcome. The output can also be manipulated by having different settling time by designing the load resistance value.
