Full textThis thesis treats the behavioural modelling of switching power devices. An original formalism has been developed where each device is considered as a black box. While requires few parameters to be switching device. Moreover, it permits the association of different black boxes and offers a good numerical behaviour. Both the diode and the MOS transistor are modelled. Although the model of diode is based on the semiconductor equation it is original and entirely satisfactory. The model takes into account the variable capacitances and gives results which are in a good agreement with the experiment. An original result is the association of the above two models which, for the first time, make possible to simulate correctly such association. This study is an important step for the complete simulation of static power converter

Full textMoreover increasing switching frequencies of converters induces increases of high frequencies part of parasitic spectrum. As a consequence, that power electronic equipment's EMC performances are very difficult to analyse. Because it is very important to be able to separate influences of switch ON and switch OFF phases on generated frequency spectrum, we have developped a tool : ASPECT (Source's Analyse of Perturbations in Electronic CommuTation), to analyse in time and in frequency, the voltage and the current waveforms of a a very simple converter : the switching cell. The work realized in this thesis treats the problem of CEM in static converter by identifying the source of perturbation : we have analyzed temporal form of commutation. ASPECT is interactive in time and in frequency, and it authorizes the different commutation study's : theoretical, experimental, simulate. We will apply our tool for helping the engineer in his choice of a cell taking electromagnetic disturbances and losses into account

Full textWhether in the context of digital communications, radar or electronic warfare, the transmission and reception chains performing these functions are made up of non-linear components. The latter carry out on the signals of interest the crucial operations of amplification, frequency transposition, and conversion from the analog world of propagation of these signals to the digital world of their processing. In all the contexts mentioned, the instantaneous dynamics is a key performance criterion, determining the spectral leakage at transmission, constraining the flow rate at reception of communication signals, or qualifying the capacity to receive echoes of different powers in radar.Increasing the instantaneous dynamics can be done through the design of the chains, both in the choice of components and in their ordering, and then involves a long and tedious design process, resulting in a sacrifice in terms of cost, size or consumption. The other way of increasing the instantaneous dynamics, which is the subject of this manuscript, is linearization by digital processing, based on behavioral modeling of the transmission or reception chain.This linearization is based on three intrinsically intertwined phases, behavioral modeling, identification of model parameters, and compensation of non-linear faults. After introducing the application context of this work, we begin this manuscript with the development of continuous-time models, based on the derivative of the signal. We thus opt to escape from the formalism of the Volterra series, based on the concept of memory effect, in order to rediscover the physical intuition of the description of the distortion with respect to instantaneous variations of the signal. We then split the identification of the parameters of these models into two phases. Characterization, first of all, brings together methods based on multi-tone signals, combining a relatively simple formalism and easy implementation. This first phase is therefore applied to the study of non-linear behavior, and to the sizing of the model. The second phase, calibration, designates the identification of the parameters of this model from white noise, by correlation, therefore requiring a heavier formalism but allowing a more exhaustive identification, intended for an embedded deployment on FPGA. As such, a first rewriting of the proposed model is introduced, on the basis of orthogonal functions, for the diagonalization of the correlation system. A second rewriting is carried out to apply the theory of multi-rate filtering to the elimination of the aliased distortion in the sampling band. The last object of this thesis work is the application of the methods presented to the realization of a calibration implemented in situ, so as to be able to adapt dynamically to the variation of the non-linear distortion of the chain with regard to the evolution of the airborne radar environment. This implementation assumes the use of the transmission chain in order to inject the calibration stimulus into the reception chain. We thus propose a method allowing the distinction of the non-linear contributions of the transmission and reception chains to the observation of the output of their cascade, in order to identify only the defects of the reception chain, for the linearization of the signal captured by the antenna

Full textPassive components, such as resistors, chokes and capacitors, are widely used in power electronic applications, especially in EMI passive filters. The parasitic elements of these components and the impact of operating conditions (temperature, voltage and current) on their frequency behavior are very significant and should not be neglected; these unwanted effects have a major impact on the global passive circuit performances. This thesis deals with characterization by measurement and modeling of passive components used in power electronics devices, with the aim of estimating and controlling the electromagnetic compatibility of such devices. The thesis was conducted in collaboration with the VeDeCoM and IRSEEM Institutes, including several industry partners of the automotive and avionic sectors. This thesis describes an experimental / modeling approach towards the production of sophisticated models of passive devices, with the inclusion of operational conditions (like temperature effects). The new models are simulated for several values of temperature and load conditions, the obtained results are compared to the experimental measurements in the frequency domain. The developed models are then translated to VHDL-AMS language for an easy implementation in most electrical simulation softwares. Finally, these behavioral models of passive components are subsequently used to model a structure of an EMI filter by integrating the variations of its operating temperature. This model is validated experimentally by comparing, under different constraints, the real behavior of the filter with the simulation results of its developed model

Full textOptimization of the "antenna - system" association is a major concern of UHF RFID tag designers. The mutual evaluation of the collected and the re-radiated power by the tag antenna makes possible system performance evaluation, early in the design flow. Thus, we develop VHDL-AMS models of RFID systems at different abstraction levels. Those models include the antennas and the RF link. The main advantage of using the VHDL-AMS language is that it is widely used within the computer-aided design tools and that this language is compatible with the microelectronic design flow

Full textOrganic photovoltaic (OPV) cells are technologies that use semiconductor materials to generate photocurrent from incident light on the device. The first process in the photovoltaic effect is light absorption, when photons of light interact with electrons of molecules in the active layer. So, it is suitable to work with materials that have light absorption in the range of the highest intensity solar irradiance, such as conjugated systems, which aromatic rings create overlaps of π-orbitals, facilitating the delocalization of electrons along the polymer backbone.Ab initio modeling is a powerful technique to design materials at the atomistic level and predict electronic properties such as optical and electronic gaps, electronic affinity and ionization potential, that are strongly related to the OPV performance. The correlation between method and accurately estimation of these properties is well known. Designing a novel molecule from computational investigation requires a deeply understanding about parameters of the polymer structure, combining blocks with different chemical functions to tune optoelectronic properties.In this work, we present a theoretical study targeting trends of such properties from a benchmarking, for a series of compounds: PM6, PTBT-Th, P3HT, C/CPCT-T-BT-T, CPT-BT, Si/CPT-TPD, BDT2-T-ffBT-T, BDT2-T-BT-T, BDT2-T-HTAZ-T, Si/CPDP-T-BT-T, and other polymers based on fused-aromatic rings such as oxybenzodithiophenes, benzotriazoles, piazthiolebenzothiadiazole and N-isopropylcarbazole. The calculations based on density functional theory (DFT) and time-dependent DFT (TD-DFT) were carried out using Gaussian16, B3LYP functional and a 6-31G(d) basis set. This thesis counted with intense explanations about optical and electronic properties and demonstrations of correlated parameters, clarifying terminologies vastly used to materials for photovoltaic applications. Other approaches based on electron density were also considered to give support to visualization analysis of noncovalent interactions.We have found, through optimisations carried out on self-assembled molecular systems, that the interactions of π systems between neighbouring molecules have a greater impact on the optoelectronic properties than the side chains attached to them. We have thus shown that it is possible to replace long branched side chains with methyl groups, reducing the computational cost without any major change in the results. The post-computational treatment of the set of interactions was carried out using the independent gradient model (IGM) and showed that it is possible to distinguish the key interactions responsible for stabilising self-assembled (macro)molecular systems as they must exist in the conducting polymer of OPV devices.This thesis has mainly enabled us to establish how the molecular structure of aggregates affects the electronic properties of a system. With this work, we presented the main assumptions of how molecular structure can affect the electronic properties, then to guide researchers on designing a new material with a high light absorption
