The presently disclosed subject matter provides thermoelectric power generating systems that can include an arrangement of power generator units electrically connected to provide a global output voltage, each power generator unit generating an individual output voltage, and an electronic stabilization system. The electronic stabilization system can include DC/DC converters connected to one or more of the power generator units; electrical variable detectors including at least one of voltage detectors and current detectors for automatically measuring the individual voltage or individual current existing at a point of a DC/DC converter; and a microprocessor-based controller connected to the voltage and/or current detectors to receive the measured voltages and/or currents, and, based on the measurements, to control the operation of the DC/DC converters to obtain desired DC/DC converter output voltages and/or desired DC/DC converter currents.
