In order to improve the efficiency of power supply systems, it is promising to use the principle of trigeneration based on the simultaneous generation of electricity (for powering electronic devices), as well as heat and cold by thermo-electric methods (for controlling the temperature of various objects). A block diagram of an energy-saving trigeneration system based on thermo-electric modules (TEM) is proposed. A generalized hierarchical model has
been developed for the study of trigeneration systems and thermoelectric systems (TES) based on multilayer Peltier elements. The model allows us to equivalently represent and analyze TES containing several control channels, local and general feedbacks, as well as nonlinear and frequency selective links, when the system is affected by external
and internal disturbances. The performed simulation of TES based on the hierarchical model and piecewise linear approximation has shown the effectiveness of the approach for analyzing nonlinear modes of TES with complex structure.
