The objective of this proposal is the advanced investigation and testing of various innovative approaches to increase the electrical output power of thermoelectric energy systems. In the first project, the efficiency of thermoelectric waste heat recovery was determined under realistic conditions. For this purpose, a multi chamber calorimeter was constructed, so that different thermoelectric modules have been examined. The improvement of the efficiency was carried out by an inverter with maximum power point tracking (MPPT). In the project a thermo generator (TEG) consisting of 12 modules was exemplarily constructed and tested. An electrical circuit has been developed which converts the output of thermoelectric module network in a maximum output electric power. The efficiency of 3.3 % (at temperatures up to 200 ° C) was obtained. An open question is the efficiency improvement at higher temperatures (T> 200 ° C).

该提案的目的是对各种创新方法进行先进的研究和测试，以增加热电能源系统的电输出功率。在第一个项目中，热电余热回收的效率是在现实条件下确定的。为此，多室量热计的构造，使不同的热电模块已被检查。采用最大功率点跟踪（MPPT）的逆变器提高了效率。在该项目中，示范性地建造和测试了由12个模块组成的热发电机（TEG）。研制了一种将热电模块网络的输出转换为最大输出电功率的电路。获得了3.3%的效率（在高达200 ° C的温度下）。一个悬而未决的问题是在更高温度（T> 200 ° C）下的效率改进。
