In recent years, there is an increasing demand of renewable energy technologies as well as the optimization of the alternative fossil resources to the upper limit. Thermoelectricity provides the opportunity to convert thermal energy directly into electricity and represents one way to harness yet unused waste heat, for example from various industrial processes, the exhaust gas system of vehicles or even from body heat.

The Linseis TEG Tester is a measurement system for temperature dependent conversion efficiency evaluations for thermoelectric generators (TEGs). Due to the temperature setting point, a gradient is applied across the thermoelectric device and the heat flow through the reference block into and out of the TEG is measured.

The generated voltage and current is scanned on different points, in less than 10 msec, to get the I-V curves or operate the TEG under a dynamic load. Hence it is possible to calculate the efficiency and track the maximum power point using the perturb and observe method.

Applications:

• Performance testing of thermoelectric modules

• Evaluation of maximum power generation and conversion efficiency

• Long-term lifespan testing under load and thermal cycling

Features:

• With a dynamic Load

• Constant current / constant voltage

• I-V Curve scanning / IC Tracing

• Maximum power point tracking (MPPT)

• Automatic mechanical load with pressure compensation

• Different modes of operation (CC, CV, FOC, MPPT, P&O)
