Direct AC/AC power converter for wind power application

Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010
Split drivetrain configurations with multiple generators are one of the solutions for increasing the reliability and reducing the cost of wind turbines. The split drivetrain technology gives the ability to introduce multiple generators and by that reduces the gear size and facilitates variable-speed operation.

An AC-AC power converter for custom power applications

IEEE Transactions on Power Delivery, 1996
A versatile AC-AC converter that can be utilized as a control device for custom power applications is presented. The converter has the ability to regulate bus voltage through voltage sags and overvoltages, and act as a solid state circuit breaker. Performance characteristics under typical conditions are presented along with experimental verification of

A new AC/AC power converter

2017 IEEE Southern Power Electronics Conference (SPEC), 2017
The Future Electrical Network will be based on the integration of different renewable energy sources. In this regard, modular bidirectional power converter architectures will get special attention. Galvanic isolation in such power converter architectures plays a vital role in confining faults.

Input Power Factor of AC to AC Power Converters

IEEE Transactions on Industry Applications, 1980
AC to ac power converters are static systems using solid-state switching devices that directly convert ac power of a given frequency to ac power of some desired frequency. They are used to link ac power systems of different frequencies, to provide variable power frequency supplies for ac motor drives, and to generate constant frequency power from the ...

Active AC snubber for direct AC/AC power converters

2011 IEEE Energy Conversion Congress and Exposition, 2011
While direct AC/AC converters like matrix converters have been around for a while, their applications are generally limited to low voltages due to complexity and issues in scaling to high voltages, including inadequate fault tolerance, complex switching patterns where errors can lead to device failures, and complex gate drive requirements for voltage ...
