摘要： A multilevel converter includes at least one phase each including several cascaded basic units each including a first switching element, a second switching element, and a separate and electrically isolated DC source (SDCS). The SDCS is electrically coupled between the first switching element and the second switching element in each basic unit. Each of the adjacent pairs of the basic units are electrically crosswise coupled together by electrical coupling of the first switching element of a first basic unit of the two adjacent basic units to the second switching element of a second basic unit of the two adjacent basic units, and electrically coupling the second switching element of the first basic unit to the first switching element of the second basic unit.

摘要： The present subject matter is directed to systems and methods for interfacing variable speed generators to a power distribution grid. A plurality of doubly-fed induction generators (DFIG) are provided and coupled to a common shaft of a prime mover. Each of the plurality of DFIGs provides an electrical power output having an output frequency based on a rotational speed of the common shaft. A converter coupled to each DFIG provides variable excitation signals to its respective DFIG sufficient to adjust its output frequency to conform to a power grid frequency requirement.

摘要： A control system for controlling a multiphase power converter includes a current control module, a voltage control module and a current command selector. The current control module generates grid voltage command signals for the multiphase power converter and the voltage control module generates reference converter current command signals for the current control module. The current command selector supplies active and reactive current command signals from a supervisory controller to the current control module when the multiphase power converter is connected to the grid and supplies the reference converter current command signals to the current control module when the multiphase power converter is unconnected to the grid.
