Повний текст джерелаL’objet de cette thèse est l’étude de l’émission champ proche temporel rayonnée destinée pour les applications CEM. Tout d’abord, le chapitre 1 présente la synthèse des méthodes de la modélisation fréquentielles et temporelles et de la mesure de l’émission rayonnée en champ proche existantes dans la littérature. Dans le chapitre 2, une méthodologie fréquentio-temporelle innovante permettant l’analyse des données champ proche en temps et en fréquence est proposée. Cette méthode de calcul permet d'extraire les cartes de champ temporel à partir des données fréquentielles pour des excitations complexes transitoires quelconques. En tenant compte de l’approche FT présentée précédemment, des méthodes d’extraction et de traitement champ proche temporel comme ont été établies dans le chapitre 3. Elles ont été développées à partir de la théorie du spectre d’onde plane en combinant avec les propriétés fondamentales des ondes planes comme l’orthogonalité, la propriété de translation d’onde plane et la relation de Maxwell-Ampère. Ensuite, une extension de la méthode inverse de modélisation des émissions champ proche à base des réseaux de dipôles EM élémentaires vers le domaine temporel fait l’objet du chapitre 4. Toutes les approches proposées ont été validées par des simulations et des mesures avec les circuits passives RF / micro-ondes. Comme prévu, les très bons résultats ont été trouvés pour chaque méthode présentée dans cette thèse. Par ailleurs, dans le dernier chapitre, une technique de mesure du champ proche totalement temporel est proposée et décrite en détail, y compris la technique de calibration. Afin de vérifier l'efficacité du banc de test, les expérimentations ont été réalisées avec différents signaux d’excitation ultra-courte ayant ns-temps de durée

Повний текст джерелаModern power systems time-domain simulations require important computational resources due to the resulting differential algebraic systems dimension and stiffness. In addition, some simulated signals oscillation frequency dramatically limits the classical schemes step size, even in steady-state during which they are close to sinusoids oscillating at system nominal frequency. That's why the sinusoidal predictors method proposed in this thesis aims at taking this property into account in order to enhance solver performances while controlling the integration error. It consists in decomposing the solution into two parts: a sinusoid, whose Fourier coefficients are fixed for each time integration interval and then updated by parametric estimation, and a correction term on which the DAE system is rewritten and solved using an adaptive step size integration scheme. A particular focus has been given on the estimator choice, given its precision direct impact on the step size and its indirect effect on the global method stability. The finally developed estimator consists in computing Fourier coefficients minimizing a system stationarity measurement. As it converges in steady-state, the correction term is progressively damped, which enables to considerably increase the step size. This method, integrated into the reference solver SUNDIALS IDA and interfaced with an industrial simulation engine, enables to very significantly accelerate simulations in comparison with a classical implementation

For broadband scattering characterization of periodic structures, numerical codes are developed. The introduced method is improved with the employment of developed FDTD codes to the proposed method. By taking the limitations regarding production facilities into consideration, a five-layered circuit analog absorber is designed and manufactured. It is shown that the manufactured structure is capable of 15 dB reflectivity minimization in a frequency band of 3.2-12 GHz for normal incidence case with an overall thickness of 14.2 mm.

Повний текст джерелаTransformadores de potência são dispositivos fundamentais para a operação de sistemas de potência e têm um peso significativo no custo total de uma instalação. Além dos custos de manutenção e substituição, as falhas nos transformadores devem ser levadas em consideração, no sentido de manter tanto a continuidade do fornecimento de energia como os padrões mínimos de qualidade estabelecidos para o insumo energia elétrico, aliado ao equilíbrio financeiro das empresas. Estudos realizados por concessionárias de diversos países deixam evidentes os enormes prejuízos financeiros das empresas do setor elétrico, devido às falhas mecânicas em transformadores. Defeitos provocados pelos esforços mecânicos decorrentes de correntes de curtos-circuitos passantes e correntes de inrush se constituem como importantes causadores de falhas em transformadores. Os esforços adicionais causados nos condutores/bobinas de transformadores, devido ao acréscimo das forças eletromagnéticas resultantes, podem, em alguns casos, vir a reduzir a vida útil de transformadores ou até mesmo provocar a sua perda total. A investigação dos efeitos danosos causados pelos fenômenos mencionados, portanto, torna-se imperativa. Nessa perspectiva, a presente tese tem por objetivo investigar as forças eletromagnéticas e o estresse mecânico resultantes de cor- rentes de curtos-circuitos passantes e correntes de energização que se estabelecem no interior de transformadores. Para alcançar tal propósito, é empregada uma modelagem computacional no domínio do tempo baseada em forças magnetomotrizes e relutâncias magnéticas. Este modelo permite simulações de fenômenos de regime transitório e per- manente, além de possibilitar o acesso às grandezas elétricas, magnéticas e mecânicas. A metodologia é aplicada a dois modelos de transformadores operando em condições nominais e em curto-circuito. Devido às dificuldades de se encontrar publicações que contenham valores de referência para validar a metodologia proposta, os resultados são comparados aos correspondentes obtidos de um tradicional e bem aceito pacote do Método dos Elementos Finitos. Os resultados oriundos das simulações são avaliados em termos do grau de impacto que é provocado nas grandezas utilizadas para aferir os esforços mecânicos a que fica submetido um transformador, quando de sua energização ou na ocorrência de curtos-circuitos passantes. A partir dos esforços mecânicos determinados é apresentada uma proposta de metodologia que estabelece uma correlação entre os fenômenos aqui estudados e o impacto sobre a vida útil de transformadores, que pode auxiliar, de maneira preditiva, na redução do número de falhas inesperadas e, em conseqüência, nos prejuízos financeiros decorrentes.

Повний текст джерелаThe capability of a radar transmitter to ensure clutter rejection depends mainly on its pulse-to-pulse stability, which is affected by many factors such as mechanical, thermal, and electrical effects. However, the P2P stability of a pulsed radar transmitter is linked to that of its power amplifiers, and more specifically on the active device technology. In this context, thiswork presents the analysis of this radar criterion at device level (GaNHEMTtransistor) in the case of a radar burst of RF pulses. A new on-wafer time-domain envelope measurement setup based on a 4-channel THA receiver has been developed to characterize pulse-to-pulse stability and the low-frequency drain current. While this setup was originally developed to characterize the critical specification of pulse-to-pulse stability for radar applications, it demonstrated a great potential for trap modeling in addition to the different characterization techniques of traps (pulsed I-V, low-frequency dispersion of Y22)

ABSTRACT Major contributions presented in this dissertation are twofold: 1) A new and simple modeling approach, namely numerical-time reciprocal state modeling (NRSM), to large-signal dynamic simulation for resonant converters (RCs) is proposed. This dynamics information is quite significant in designing actual component ratings and high performance converters; however, it is not available in the literature for the fourth-order RCs. Because the approach only needs three relatively straightforward operations, which can be done by inspection only, to formulate numerical-time state equations for a simulation program, it is probably the simplest approach. Though the proposed approach is very simple (c.f. [29]), it provides an exact solution to the numerical-time model. These combined advantages of simplicity and accuracy would make this approach quite attractive in the study of dynamic behavior of such converters. 2) Combining the numerical-time state models for energy-storage elements with unification models of switching devices and several straightforward circuit-manipulated operations, a new and simple formulation method is proposed for power electronic circuits to obtain a reduced unification matrix (RUM). Simulation results using the RUM method demonstrate its superiority over the commonly-used MNM method, not only for memory requirements but also for computational speed. A large circuit example shows that the RUM method offers a 76.32 percent timesavings in computation. These combined advantages should make the proposed RUM method very attractive in the time-domain simulation of switched networks. For large switched networks, the decided advantages are very great.
