摘要：
A method for powering a pitch motor drive system for at least one DC pitch motor of a wind turbine includes rectifying a voltage using a bridge circuit to thereby supply a DC link voltage to a bridge comprising active switching devices, and utilizing at least one link capacitor to smooth the DC link voltage and act as an energy sink and source for the DC pitch motor or motors.
