The DC/DC converter is the core part of the two-stage electric vehicle Onboard Charger.At present, the phase-shifted full-bridge soft-switching DC/DC converter has problems such as difficulty in commutation of the lagging leg, voltage fluctuation on the secondary side of the transformer, Sweeteners and low efficiency.A full-bridge DC/DC converter w
We explore a portfolio constructive model, formulated in terms of satisfaction of a given set of technical requirements, with the minimum number of projects and minimum redundancy.An algorithm issued from robust portfolio modeling is adapted to a vector model, Jeans modifying the dominance condition as convenient, in order to find the set of nondom
Acoustic emission technology has been applied to many fields for many years.However, the conventional piezoelectric acoustic emission sensors cannot be used in extreme environments, such as those with heavy electromagnetic interference, high pressure, or strong corrosion.In this paper, a novel fiber-optic ring acoustic emission sensor is proposed.T
Barn owls, members of the family Tytonidae, are unmistakable nocturnal birds of prey.Their ghostly appearance and blood-curdling shriek have led to their incorporation into folklore and myth and Chair have earned these birds a variety of nicknames, including "ghost owl" and "monkey-faced owl." Thirty-six subspecies have been identified worldwide.Th
