Modeling and Testing of Thermoelectric Generator Based Energy Harvester for Powering Wireless Sensor Node Used in Condition Monitoring System for HVDC Converter

This paper focuses on the modeling and testing of a thermoelectric generator (TEG) -based energy harvester for powering wireless sensor nodes in a high-voltage direct current (HVDC) converter. The objective is to investigate the feasibility of using an environmental power-based energy harvesting solution for powering wireless sensor nodes in harsh industrial environments. The paper firstly models the thermoelectric generator, and then the experimental validation of the TEGbased energy harvester is carried out in a real HVDC converter module. The results prove the feasibility of using a thermoelectric generator as an energy source for powering wireless sensor nodes in condition monitoring for HVDC converter.
