Zusammenfassung:	Systems 100 and methods 300 for controlling a wind pitch adjustment system associated with a wind turbine system are disclosed. In one embodiment, the wind pitch adjustment system 100 can include a power supply 104 configured to convert an alternating current input signal into a direct current voltage, a controller 106 configured to receive a signal from the power supply, and to provide one or more control commands to a pitch adjustment motor 32, and a surge stopping device comprising a switching element coupled between the power supply and the controller 106. The surge stopping device 104 is configured to monitor an input voltage from a grid and to drive the switching element based at least in part on the monitored input voltage, such that the switching element is configured to block current flow through the switching element to the controller 106 when the monitored input voltage is above a voltage threshold.
