The paper reports the results of an experimental investigation of a five-phase two-motor drive system, consisting of a parallel connection of two induction machines (IM). Thanks to an appropriate connection of the motors, two machines are controlled indepe ...
Micro Aerial Vehicles (MAVs) with perching capabilities can be used to efficiently place sensors in aloft locations. A major challenge for perching is to build a lightweight mechanism that can be easily mounted on a MAV, allowing it to perch (attach and de ...
The paper presents a methodology to determine the coefficient of the natural convection for the surface of a small electric motor. The theory of natural convection is applied to obtain analytical formulas, and the radiation is incorporated in the model. Th ...
A one-pot procedure involving radical conjugate addition of B-alkylcatecholboranes to enones followed by intramolecular aldol reaction is reported. Application to the stereoselective synthesis of monocyclic and bicyclic products with up to four contiguous ...
Electric vehicles are mainly fed directly from batteries, where the high power solicitation represents a well-known problem with its relation to efficiency and life cycle of batteries. The paper presents experimentation and study of a solution with power a ...
The current development of generators and power electric drives is characterized by increased power electronic integration. This evolution concerns particularly the variable speed power units allowing both a higher performance and substantial savings on co ...
This paper presents the modeling, detailed simulation, and test of an efficient medium-voltage adjustable-speed drive. The system consists of a three-level neutral-point-clamped inverter supplied by a 12-pulse rectifier. To achieve a motor-friendly supply, ...
The choice of the drive composition is an obligatory stage in designing a product including electric drives. The large variety of the elements composing the electric drive (electronics, driving and kinematic chain) leads to a quasi-unlimited number of poss ...
The research discussed in this article is motivated by the search for an optimal classification of the different types of atrial fibrillation (AF) on the basis of recorded atrial signals. This would facilitate the selection of an optimal therapy. This arti ...
In the field of PLC, the standardization process on international level is progressing very slowly. The EMC Laboratory of the North China Electric Power University has received the task to develop a measurement method for the field radiated by PLC installa ...
