摘要： Systems, power modules (108), and methods (200) for using in controlling a converter (110) coupled between a power generator (104) and an electric grid (102) are provided. One of the power modules (108) includes the converter (110) configured to supply an output from the power generator (104) to the electric grid (102), and a controller (112) coupled to the converter (110). The controller (112) includes a phase-lock-loop (PLL) module (123) and at least one regulator (128, 130). The at least one regulator (128, 130) is configured to at least partially control the converter (110) as a function of at least one parameter. The controller (112) is configured to disable the converter (110) in response to a grid fault event, to maintain coupling between the power generator (104) and the converter (110) during the grid fault event, to determine whether the PLL module (123) is locked onto a voltage associated with the electric grid, to adjust the at least one parameter after the grid fault event, and to re-enable the converter to supply the output from the power generator (104) to the electric grid (102).
