FIELD: electricity.
SUBSTANCE: invention is related to the field of electric engineering and power electronics and can be used for design of alternating-current generation systems or AC uninterrupted power supply systems with a voltage inverter. In the suggested method for control of a static converter in an alternating-current generation system in short-circuit conditions load current is measured and when it reaches the preset value a control signal for the voltage converter is changed providing the maximum value of short-circuit current thus regulating the direct-current value at the inverter input, stabilising short-circuit current in the load during a certain period of time.
EFFECT: providing selectivity of loads shedding where short-circuit conditions occur, improving service life of the system and reducing active losses in the voltage inverter in short-circuit conditions.
