Control and cooling of the electronic load solution based on FET-transistor

On the basis of the previously considered physical and circuit solutions for the implementation of the electronic load unit, its cooling and control system was developed. The calculation of the heat balance allows you to choose the right cooling system for stable operation of the system. The control of the electronic load unit is implemented using INA219 and Xicor X9C microcircuits, and a method for their calibration is proposed. These solutions will make it possible to create a universal electronic load solution for researching semiconductor devices and solar cells.
