Copy of Calibrate TEC/TEG for Energy Harvesting - on Sat, 12/05/2020 - 22:11 Designer https://explore.partquest.com/node/387610 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/387610"></iframe> Title Description <p>This example shows the effect of sweeping the load resistance from 0 to 10 Ohms. The rate of change is one Ohm per second, so that the time value corresponds to the instantaneous load resistance value. The example TEC/TEG represents a CUI CP60340 Peltier Module.</p> <p>The TEC appears to be capable of generating approximately 0.9 Watt (maximum power, see magenta waveform) with a temperature differential of 75 degC and perfect thermal coupling, and the hot side at a constant 100 degC.</p> <p>This test schematic can be reused to calibrate other TEC/TEG models and under various differential temperature and loading conditions.</p> About text formats Tags PeltierTEGThermoelectricSeebeck Select a tag from the list or create your own.Drag to re-order taxonomy terms.
