| Abstract: | The grid-connected inverter is important for energy conversion and transmission, of which the performance has a direct influence on the entire wind power generation system. The mathematical model of the grid-connected inverter is built firstly. Furthermore, the space vector pulse width modulation is analyzed. The adjustability of the power factor is realized based on current close-loop and grid voltage vector oriented control. The control strategy is verified by the simulation and experimental results with good sinusoidal current ,small harmonic component and a fast dynamic response. |

| Keywords: | grid-connected inverter space vector pulse width modulation grid voltage vector oriented power factor |
