Beschreibung
Zusammenfassung:	The invention discloses a driving power supply of a wind turbine generator pitch variable system. The driving power supply comprises a controller, a direct current power supply, a transformer, a voltage driving type switch connected with a pitch variable system motor, and a driving chip capable of controlling on-off of the voltage driving type switch; the signal input end of the driving chip is connected with the signal output end of the controller and used for receiving a pitch variable signal from the controller; the driving power supply also comprises a power supply chip with the model of VIPer22AS and a current-limiting resistor; one end of the current-limiting resistor is connected with the power supply positive end of the direct current power supply while the other end is connected with a sampling voltage input end of the power supply chip; an internal circuit power supply pin of the power supply chip is connected to the power supply positive end of the direct current power supply; the field effect tran
