This paper presents a multiphase induction system modeling for a metal disc heating and further industrial applications such as hot strip mill. An original architecture, with three concentric inductors supplied by three resonant current inverters, leads to a reduced element system, without any coupling transformers, phase loop, mobile screens, or mobile(More)
. This study considers a Hybrid Electrical Vehicle supplied by a Fuel Cell stack and supercapacitors used as Storage Element. In such an application, real time energy management is of paramount importance in order to increase autonomy and be able to deal on-line with perturbed power demand. Many offline power flow optimization principles are available but(More)
This paper presents a robustness study of the current control scheme for a multiphase induction heating system. Resonant control has been chosen in order to achieve a perfect current reference tracking in the inductors with different solutions from the literature. A simplified model of the system is given; it is based on data extracted from finite-element(More)
This paper presents different methods and approaches allowing a better energy management for Hybrid Electrical Vehicle presenting a multi-source system, in order to increase its autonomy, reduce the costs of its energy consumption and decrease pollutant emission. The main goal sought is to minimize the battery discharge allowing the vehicle to make a(More)
This paper deals with the setting parameter optimization procedure for a multi-phase induction heating system considering transverse flux heating. This system is able to achieve uniform static heating of different thin/size metal pieces without movable inductor parts, yokes or magnetic screens. The goal is reached by the predetermination of the induced(More)
This paper presents the steps of the approach to identify the linear parameters of a salient-pole synchronous machine at standstill and by frequency response tests data (SSFR). It is currently established and demonstrated that stability parameters for synchronous machines can be obtained by performing frequency response tests with the machine at standstill.(More)
This paper describes the process of electrical energy management and optimization in a multi-source system such as a Hybrid Electric Vehicle (HEV), running on a known mission profile. The purpose of the committed study is to minimize the consumption of the fuel used by one of the sources, to respect the different constraints related to the operating system(More)
Attention is focused in this paper, on the Matsuipsilas position observer structure, which is based on the back emf estimation for a permanent magnet synchronous machine. This structure includes gains and filters that have to be tuned, in order to reach the best possible convergence. An optimized experimental tuning of these gains in different PMSM(More)
Minimizing the consumption of hydrogen by a fuel cell system in a hybrid vehicle can reduce its environmental impact and increase its autonomy. However an intelligent management of power distribution is essential to meet the demand of the powertrain. The characteristics of the sources constituting the energy chain of the hybrid vehicle (efficiency and(More)
