Zusammenfassung:A pitch control system 30 for a wind turbine 10 is disclosed. The pitch control system 30 may generally include a motor 102 having an armature 104 and a winding 106 and a grid power source 110 configured to supply electrical power to the motor 102. The pitch control system 30 may also include a plurality of switching components 120, 122, 124 configured to control a first current through the armature 104 independent of a second current through the winding 106. In addition, the pitch control system 30 may include an auxiliary switching component electrically coupled between the grid power source 110 and at least a portion of the switching components 120, 122, 124. The auxiliary switching component may be configured to be opened when a grid voltage of the grid power source 110 exceeds a first voltage threshold.
