    摘要: An apparatus for controlling overcurrent of a grid-connected inverter due to an abnormal grid voltage includes a grid voltage sensor configured to sense a grid voltage according to an output current of the grid-connected inverter, a voltage variation calculator configured to calculate a D-axis voltage and a Q-axis voltage of the grid voltage to obtain variation values of the D-axis voltage and the Q-axis voltage, and an output current controller configured to determine whether at least one of the D-axis voltage variation value and the Q-axis voltage variation value exceeds a set value of the grid voltage variation, and decrease the output current by a predetermined value when one of the D-axis voltage variation value and the Q-axis voltage variation value exceeds the set value of the grid voltage variation.
