摘要： A system for controlling a grid connected power generating system (90) is provided. The system includes a wind turbine (42, 12), a converter (14, 16), a first controller (18) and a second controller (154). The wind turbine supplies electrical power to a power grid (22) and the converter (14, 16) couples the wind turbine to the power grid. The first controller (18) calculates voltage commands to emulate a phasor back electromotive force behind an inductance. The controller further generates converter switching commands from the voltage commands. The voltage commands include a voltage magnitude reference and an internal frequency reference calculated from a power imbalance between an active power reference and the electrical power. The second controller is used to limit a converter current.

摘要： Systems 10 and methods 300 for converting power are presented. The power conversion includes conducting load current through a first current path 92 of multiple current paths in a power conversion unit 12 using switches 60, diodes 74, or a combination thereof. The power conversion also includes blocking one or more additional current paths 94 of the multiple current paths in the power conversion unit 12 using one or more of the switches 60, one or more of the diodes 74, or a combination thereof. Furthermore, the power conversion includes reducing potential voltage stress on the one or more switches 60 by using one or more voltage stress reduction switches to reduce a voltage that is blocked by the one or more blocking switches or diodes 74 by connecting an end of each of the one or more switches 60 opposite to a blocking edge to an intermediate voltage node 84.

摘要： A power converting apparatus and method providing for the addition of a fourth power connection wire to the neutral point of the normal three phase load circuit (105). This allows delivery of combined current from the center of the DC link voltage to load. The added control enables a third harmonic injection to flow and allows for increased power rating per peak amp handled by the conversion system. Limiting of faults to the positive half versus the negative half of the DC system allows for more robust behavior when encountering these fault conditions.
