摘要： A bi-directional power converter apparatus and method of conversion is disclosed which comprises three active elements (output, primary, and auxiliary switches) and two passive components (primary and auxiliary energy storage elements) coupled so as to enable operation in any one of several different power conversion modes, including: a Non-Assisted Generation mode, a Super-Assisted Generation mode, a Super-Assisted Regeneration mode, an Auxiliary Generation mode, and an Output Regeneration mode. The individual components operate in a synergistic fashion to enable the free, bi-directional, transfer of power from primary and auxiliary energy sources to a load, and from the load to the primary and auxiliary energy sources. Further, the invention operates in such a way as to dramatically reduce the effective boost/buck ratios required for low voltage energy sources connected to a high voltage output power bus.

摘要： A method for detecting and preventing islanding includes issuing a command to an inverter connected to a power source, where the inverter is coupled to a power grid and supplies power to the power grid, the command causes a frequency of a waveform output by the inverter to vary, and the frequency of the waveform output by the inverter is a command frequency, determining that a amount of change of the command frequency is a constant value for a predetermined amount of time, removing the power supplied by the inverter from the power grid, and determining whether the power grid is valid.

摘要： Various examples are directed to systems and methods for detecting an islanding condition at an inverter configured to couple a distributed generation system to an electrical grid network. A controller may determine a command frequency and a command frequency variation. The controller may determine that the command frequency variation indicates a potential islanding condition and send to the inverter an instruction to disconnect the distributed generation system from the electrical grid network. When the distributed generation system is disconnected from the electrical grid network, the controller may determine whether the grid network is valid.

摘要： A variable speed, constant frequency (VSCF) system utilizes a doubly-fed machine (DFM) to maximize the output power of the system. The system includes a power converter that provides a frequency signal and a current signal to the DFM. The power converter is controlled by an adaptive controller. The controller signals the converter to vary its frequency signal and thereby the rotor speed of the DFM until a maximum power output is sensed. The controller also signals the converter to vary its current signal and thereby the portions of power carried by the respective windings until a maximum power output is sensed. The control can be augmented to not only maximize power and efficiency, but also provide for harmonic and reactive power compensation.
