Abstract
An apparatus for protecting a grid-connected inverter from a low grid voltage includes a first output current sensor configured to sense an output current of a grid-connected inverter, a first output current calculator configured to calculate a D-axis current and a Q-axis current of the output current to obtain the output current that is sensed, and a first output current controller configured to determine whether a difference between the output current and a reference current exceeds a predetermined range, and to decrease the output current by a predetermined value when the difference between the output current and the reference current exceeds the predetermined range.
