摘要： The present subject matter is directed to systems and methods for improving reliability of dual bridge 202 doubly fed induction generators (DFIGs) by reducing the number of required components in the converters associated with such DFIGs. A converter 186 is constructed using a pair of current conducting bridges 202, 204 wherein one of the current conducting bridges 202 is controlled and the second 204 is not controlled. The uncontrolled bridge 204 may correspond to a pair of diodes while the controlled bridge 202 may correspond to a pair of transistors, in particular, a pair of IGBT transistors.

摘要： A system (200, 300) for supplying AC power (235) from a DC power source, such as a photovoltaic array (210, 310) is disclosed. The system (200, 300) includes a converter (220, 320) and an inverter (230, 330) coupled by a DC link (325). Control methods and systems are provided to maintain the DC source voltage and the DC link voltage below the open-circuit voltage of the DC power source. During steady state conditions, the DC source voltage and the DC link voltage are maintained below the open-circuit voltage of the DC power source by controlling the output of the inverter (230, 330). The DC link voltage is temporarily adjusted to allow for higher DC link (325) transients when the DC power source is first coupled or re-coupled to the system (200, 300). During conditions when the inverter (230, 330) is decoupled from the system (200, 300), the converter (220, 320) is controlled to maintain the DC link voltage below the open-circuit voltage of the DC power source.
