—Wind energy conversion systems (WECS) nowadays offer an extremely wide range of topologies, including various different types of electrical generators and power converters. Wind energy is also an application of great interest to students and with a huge potential for engineering employment. Making WECS the main center of interest when teaching power(More)
Fault-tolerance is one of the most sought-to capabilities of wind energy conversion systems (WECS). The ability to maintain operation even after an open-phase fault, allows for the system operators to maintain energy production, providing tangible economic benefits. Recently, the use of multiphase drives for WECS have been proposed due to their inherent(More)
Retroperitoneal fibrosis (RPF) is characterized by replacement of the normal tissue of the retroperitoneum with fibrosis and/or chronic inflammation. About two-thirds of cases of RPF are idiopathic and one-third is secondary to drugs, infections (tuberculosis, syphilis, actinomycosis, fungal infections), retroperitoneal hemorrhage, or malignancy. We report(More)
