The use of Universal type motors is very commonly used, both in daily life and research activities. universal motor can be used as prime mover generator PMSG (Permanent Magnet Synchronous Generator), which its application there are obstacles, namely the difficulty stabilizing speed due to influence changes load connected PMSG, this affects output voltage generated by system. In case, a stabiliz...

This article presents a novel configuration for unified power flow controller (UPFC) comprising modular multilevel cascaded converter (MMCC) with full-bridge inverter. The MMCC has one end of each phase-leg shunt-connected to the transmission line. other connects in parallel primary terminals series line transformer, and ac output dc–ac submodules are flying capacitor converters. UPFC is compar...

The cochlear nucleus angularis (NA) is widely assumed to form the starting point of a brain stem pathway for processing sound intensity in birds. Details of its function are unclear, however, and its evolutionary origin and relationship to the mammalian cochlear-nucleus complex are obscure. We have carried out extracellular single-unit recordings in the NA of ketamine-anesthetized barn owls. Th...

Synchronous generators have always been the dominant generation type in the grid. This fact affected both planning and operation of power systems. With the fast increase of wind power share in the grid in the last decade, the situation is changing. In some countries wind power represents already a consistent amount of the total generation. Wind turbines can be classified as non-synchronous gene...
