We investigate in this paper a numerical method to control the temperature of an induction heating process through electric current parameters such as frequency and current voltage imposed to the terminals of the inductor. We seek a sinusoidal voltage func ...
A hybrid technology for the realization of threedimensional miniaturized power inductors, transformers and RF inductors is presented. This technology consists of combining planar Cu coils on polyimide substrates with high permeability and high resistivity ...
Diesel-electric traction is a well-established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel-powered locomotive is due to the reduced costs compared to the infrastructure cost of ...
Hybrid asymmetric multi-level inverters promise significant improvements for medium-voltage industrial drives. Floating sub inverters without feeding can only supply reactive power. An on-line non-linear model-predictive controller stabilizes their interme ...
Hybrid asymmetric multi-level inverters promise significant improvements for medium-voltage industrial drives. Floating sub inverters without feeding allow increased efficiency, but can only supply reactive power. An on-line non-linear model-predictive con ...
This work describes a development of a control system and control strategies capable of governing multiple flexible AC transmission system (FACTS) devices. The main purposes of the presented coordinated control system are to remove overloads and to achieve ...
This paper presents results from numerical modeling of non-twisted multifilamentary Bi-2223/Ag conductors with various geometry and filament arrangement. Anisotropic models of Jc(B) and n(B) have been employed in finite element method simulations under dif ...

Recent power quality studies have been focused on the source-identification of voltage disturbances at distribution network busses. This paper describes a method aimed at correlating indirect-lightning events with power systems relay operations, associated ...
Supercapacitors are components for energy storage. Due to their series resistors, the energy efficiency of supercapacitors can be low. In this paper, the unloading of supercapacitors with constant current and power are studied, to identify and take into ac ...
