Patent attributes
A wind power converter includes a multiple of phase power converters, each of which being adapted to convert power output from a corresponding phase of a wind generator to a corresponding phase of a grid. Each of the phase power converters includes a full-wave rectifier, being adapted to rectify the power input through a first terminal and a second terminal from the corresponding phase of the wind generator; a capacitor being adapted to be charged by the power rectified by the full-wave rectifier; and a full-wave active inverter, being adapted to invert the power stored in the capacitor and output the inverted power to the corresponding phase of the grid through a third terminal and a fourth terminal. The first terminal or the second terminal is connected to a first virtual neutral; and the third terminal or the fourth terminal is connected to a second virtual neutral. By having such topology, each phase power converter serves as a power conversion module independent of the others. Thus, the electrical coupling between any two of the phase power converter is removed. The details of the phase power converter will be described thereafter. It is therefore an objective of the invention to decrease the cost and at the same increase the feeding electrical power quality.
