Common Mode Choke Charactérisation method and modelling for EMI filter in Power Electronics

An equivalent circuit has been developed to model the linear electrical behaviour of any two windings common mode chokes. Its topology is independent of size and technology and a general method of characterization, exclusively based on external…

Improvement of the magnetic core for eddy current losses decreasing in cylindrical linear actuators

In this paper, a method for reducing the eddy current losses in cylindrical linear structure is presented. It is based on one or several slots in the magnetic circuit. This method has been applied in a multi-rod actuator. The comparison between…

Force Density Improvements from Increasing the Number of Airgap Surface in Synchronous Linear Actuators

This paper presents a realistic comparison of several electromagnetic architectures for high force density actuators. Four equivalent architectures are chosen and computed with a two-dimensional finite element model. For each architecture, size is…

Optimization Material Distribution in Electromagnetic Actuators

In this paper, a new approach for Optimization Material Distribution is proposed. The principle behind this approach is to use a surface genetic algorithm in order to determine material distribution in a fixed Finite Element Computation mesh. The…

Modélisation et optimisation des performances CEM d'une association variateur de vitesse – machine asynchrone

Today, Electromagnetic Compatibility seems to be one of the major constraints of power electronics converters and especially for variable speed drives. Unfortunately, it is too often regarded as the last phase of the development of a converter since…

Energy Modeling of a Lead-Acid Battery within Hybrid Wind/Photovoltaic Systems

Within the scope of full-scale energy modeling of a hybrid wind / photovoltaic system coupled to the network, our focus herein lies in a battery set-up that makes use of the CIEMAT model. The implementation and energy-based analysis of this model…

Flywheel energy storage systems in hybrid and distributed electricity generation

In this article, we will demonstrate the benefit of the electromechanical storage of energy over long operating cycles (with time constants ranging from several minutes to a few hours), within the scope of decentralized electrical energy production…
