Study on electrical properties in generating electricity with semiconductor thermoelectric generator

文章根据塞贝克效应(Seebeck effect)、珀尔帖效应(Peltier effect)、汤姆逊效应(Thomson effect)原理,制作了半导体温差发电器系统,通过试验测试获得了在不同温度等级下的电气特性。结果表明,开路电压和负载电压随温度升高呈线性上升趋势。当温度一定时,电流随负载变化呈几何对数增长,并找到了电压越低输出功率越大的功率特性。

A novel semiconductor thermoelectric generator was made according to Seebeck effect, Peltier effect and Thomson effect. Electric properties with different temperatures were found out through experiments and tests. The results of the research proved that the circuit voltage and load voltage appeared a tendency of linear increase with the temperature. The electric current appeared a geometric logarithm increase with the change of the load when the temperature was decided. Meanwhile, the power characteristic that the power output became higher with the reduction of the voltage was confirmed.
