  • AUXILIARY CIRCUIT TO INJECT FAULT CURRENT DURING GRID FAULTS
    Publication number: 20240146050
    Abstract: An auxiliary circuit to inject fault current to a grid is provided. The circuit includes a pair of transformers including a first transformer and a second transformer, and a pair of SCRs including a first SCR and a second SCR. Each SCR remains in an OFF state and an ON state when AC voltage of the grid is in normal range and fault range, respectively. The circuit includes a capacitor electrically connected between the first transformer, the second transformer, and the first SCR. The circuit includes a diode biased by the second transformer and the capacitor to enable charging of the capacitor to a peak of AC voltage during one polarity of AC voltage when the AC voltage is in normal range. The capacitor discharges via the first SCR and the first transformer by injecting the fault current into the grid when the AC voltage is in the fault range.
