Doubly fed induction generators (DFIG) based wind turbine is an emerging technology, which becomes increasingly popular due to its various advantages over fixed speed generator systems. A DFIG based wind turbine has an ability to generate maximum power with varying and adjustable speed, ability to control active and reactive power by the integration of electronic power converters, low power rat...
The revolution in power electronics has opened an era for widespread use of power converters of different power rating from few Watts to Mega-Watts. AC-DC converters are most widely used power converters as the distributed electric power is AC supply, while the applications based on DC supply as well as variable frequency AC supply, need conversion of AC supply into DC supply. Large current har...
Most existing power converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...
This paper presents modeling and control of a microgrid based on hybrid renewable energy sources including Photovoltaic (PV), Fuel Cell (FC) and Battery Energy Storage (BES). The overall configuration of the microgrid including dynamic models of PV, FC, BES and its power electronic interfacing are briefly described. Then controllers design methodologies for power electronic converters in order ...
Increasingly more electrical devices are being developed in modern aircraft and will result in an increase in airborne electronic equipment fed by power electronic converters. With aircraft power system being sizable, the logical structure of aircraft power distribution systems, which affects the stability of aircraft power system, is becoming more complex. In this paper, we establish a mathema...
Solar power and wind are the most promising distributed energy sources. The photovoltaic system has attracted significant attention in recent years. Although their benefits are numerous, they are known to create power quality issues, because of the power electronic converters they use. This paper investigates if there is a possibility to improve power quality only by connecting a solar photovol...
