Beschreibung
Zusammenfassung:	The utility model discloses a wind driven generator yaw system which comprises a voltage detection unit, a control processing unit, an insulated gate bipolar transistor (IGBT) driving unit, a yaw frequency converter, a yaw motor, a yaw speed reducer and a yaw gear. The yaw frequency converter comprises an alternating current (AC)/direct current (DC) rectifier and a DC/AC inverter. The input end of the AC/DC rectifier is connected with an alternating current power supply, the output end of the AC/DC rectifier is connected with the input end of the DC/AC inverter, and the output end of the DC/AC inverter is connected with the yaw motor. The yaw motor, the yaw speed reducer and the yaw gear are sequentially in series connection. The input end of the voltage detection unit is connected with the input end of the AC/DC rectifier, the output end of the voltage detection unit is connected with the control processing unit, the control processing unit is connected with the IGBT driving unit, and the driving unit is con
