In this study, we established the nonlinear model order reduction (MOR) of induction motors by parameterizing a multi-port Cauer ladder network (CLN). Appropriate parameters were selected to incorporate nonlinear magnetic characteristics. The parameterized multi-port CLN was applied to the transient analysis of a rotating induction motor. The propo...
L’électrification croissante des aéronefs dans le cadre du développement de l’avion plus électrique impose de mettre en place de nouvelles méthodologies pour dimensionner les composants électroniques embarqués.Cette thèse se place dans cette perspective et envisage de poser les bases d’une nouvelle méthodologie pour le dimensionnement optimal des c...
peer reviewed / Many variable-capacitance energy harvesters employ a large inductor to improve their power efficiency by reducing conduction losses, which is sub-optimal in applications requiring a small form-factor, such as in implants. This paper describes a variable-capacitance harvester that performs optimally using miniaturized inductors. The ...
In this article, a dc-link structure feasible for integration with the circumscribing polygon modular integrated drives is proposed. The proposed dc-link structure combines both the dc-link capacitors and the bus-bar together and integrates them with the machine and the converter modules without increasing the outer diameter of the integrated machi...
The DC solid-state transformer (DCSST) is a key component of the DC microgrid, and stability issues due to operation with constant power loads (CPLs) have become increasingly prominent. To stabilize the system of DCSST with CPLs, in this paper, a novel intelligent backstepping controller based on a nonlinear disturbance observer (NDO) is proposed, ...
An interturn short-circuit in the stator windings can lead to the breakdown of electrical machines. In the case of induction machines, several fault detection methods and faulted models have been developed in the recent decades. These models differ mainly in how the leakage inductances of the faulted winding are modeled. This work provides a genera...
The zero-sequence inductance is a vital parameter for the performance analysis of permanent magnet machines, especially under faulty conditions or in open-winding machines. This paper focuses on the zero-sequence inductance calculation of fractional slot concentrated winding permanent magnet synchronous machines (FSCW-PMSMs), and reveals the variat...

In this paper, in order to amplify terahertz output pulses and achieve higher frequency peaks, a scheme of spiral lines is proposed to be used in the electrodes of photoconductive dipole antennas. This scheme is simulated with the help of the CST software. At first, a photoconductive antenna is simulated and compared with the experimental results. ...
The ability to use actuator and load models online in combination with experimental data becomes increasingly important in future electrical drives. Amongst the applications of such online model in torque and flux controllers, model predictive control (MPC) has gained increasing interest, allowing to deal in real time and in a suboptimal way with d...
