This article is devoted to the issues of building the inverter for automated determination system of semiconductor devices volt-ampere characteristics. In the article the structure of such a system is considered and it is proposed to use a half-bridge inverter with an inductive-capacitive filter to regulate the test voltage. In order to control the output current of such an inverter, it is proposed to use relay control, and control of the output voltage is proposed to be carried out indirectly through current regulation. The structure of the control device of such an inverter that implements the proposed approach to control is developed. Using the software environment MATLAB Simulink a virtual model of the inverter and its control device is built. The research of the developed system operation during the determining the volt-ampere characteristic of the semiconductor diode has been carried out. Obtained results confirmed the efficiency of the proposed approach.

Index Terms—Determination of volt-ampere characteristics; half-bridge inverter; computer simulation.
