METHOD FOR CONTROLLING THE KEYS OF A STABILISED CURRENT SOURCE IN AN ELECTRONIC SOLAR ARRAY SIMULATOR Russian patent published in 2022 - IPC G05F1/67 H02S50/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in inertia-free electrical solar array simulators (SAS) based on a DC voltage source. In the proposed method for controlling a current source in a solar array simulator containing a source of DC voltage corresponding to the idle stroke voltage, a booster voltage source and a short-circuit current source in the form of a short-circuit current stabiliser of the simulator with a throttle, a current sensor, and the keys of the primary and bypass adjustment circuits, consists in switching the keys of the primary and bypass circuits in the tolerance zone for deviation from the set current, said zone being determined by the set permissible current pulsations; with sharp drops and surges of the load of the I-V curve simulator, the primary and bypass keys are switched in the second expanded tolerance zone, wherein when the load is reset and the current value reduced below the lower level (LL) of the first tolerance zone, both of said keys are opened, and when the load surges and the current value is raised above the upper level (UL) of the first zone, both keys are locked; the ranges of the adjustment error signal are additionally set for the upper and lower levels (ΔUL and ΔLL), and if the current error signal value is in the ΔLL range, the possible LL signal to open both keys is blocked (VT_obv and VT_osn), and the possible UL signal to close said keys is passed, and if the error signal is in the ΔUL range, the possible UL signal to lock said keys is blocked, and the possible LL signal to open said keys is passed.

EFFECT: invention eliminates or reduces the effect of interference on the operation of the apparatus for controlling the current stabiliser module of the solar array simulator in order to exclude the keys closing/opening out of sequence.
