摘要（英）：

The utility model discloses a direct drive wind power generation system based on a double SVPWM current mode converter, which is characterized in that a permanent magnet synchronous generator M1 is coaxially connected with a wind machine M2, and a stator alternating current signal output end of the permanent magnet synchronous generator M1 is connected in series with a three-phase current mode all-controlled rectifier, a direct current inductor and a three-phase current mode grid-connected inverter; and all-controlled power switch tubes constituting the three-phase current mode all-controlled rectifier and the three-phase current mode grid-connected inverter are all-controlled devices, and are controlled by PWM11-PWM16 and PWM21-PWM26 space vector pulse width modulating signals SVPWM. The direct drive wind power generation system simultaneously realizes speed-change control on the permanent magnet synchronous generator and the synchronous grid-connected control on the power grid side.
