Zusammenfassung:	WIND TURBINE PITCH CONTROL SYSTEM A pitch control system for a wind turbine is disclosed. The pitch control system may generally include a motor having an armature and a winding and a grid power source configured to supply electrical power to the motor. The pitch control system may also include a plurality of switching components configured to control a first current through the armature independent of a second current through the winding. In addition, the pitch control system may include an auxiliary switching component electrically coupled between the grid power source and at least a portion of the switching components. The auxiliary switching component may be configured to be opened when a grid voltage of the grid power source exceeds a first voltage threshold. 518 44 42 52 54 46 46 (66 50,__o, FIG. -2-
