In the Quarterly Progress Report of October 15, 1957, page 52, we pointed out that we had devised a feedforward-across-the-limiter technique that could be arranged to suppress whichever of two cochannel FM signals is undesired. A simple experimental model of this system was built and tested (1). Before summarizing the experimental results, we shall present a resume of the appropriate theoretica...

The wind energy conversion technology of a Permanent Magnet Synchronous Generator (PMSG) is very promising in renewable power generation. However, the performance grid-connected PMSGs greatly affected by grid disturbances because their stator windings are interfaced with directly. There different Fault Current Limiter (FCL) topologies that capable improving Ride Through (FRT) capability PMSG tu...

Increase in power generation capacity of electric power systems has lead to increase in the fault current level which can exceed the maximum designed short-circuit ratings of the switchgear. All the equipment therefore must have a short-circuit rating capable to withstand this level. Short-circuit currents contain extremely high energy and can damage electrical equipment. Typically, the circuit...
