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 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 textThis work is dealing with the modelling of analogue and mixed signal circuits. Moreprecisely, we focus on modelling the circuits of an analogue front-end which is used in down-holedrilling industry for instrumentation and measurement purposes. This research had as a goal tomodel the temperature increasing effect in the behaviour of each circuit of the considered frontend.The studied circuits belong to the family of “conventional” circuits. Most of these circuitsoperate in a temperature which does not exceed 125°C. Even if the behaviour of the circuit changesdue to an increasing of the temperature, there are some well-know techniques that enable thecompensation of such effects. However, in order to obtain a precise simulation in the design phase,it is very important to have accurate models that describe the temperature increasing effect. Asmost of the commercial circuits models are written in SPICE, it is necessary first to review theaccuracy of SPICE models in high temperature (HT). This work focus on a specific circuit: theoperational amplifier (opamp). This device is present in many instrumentation circuits. Obtainingan accurate op-amp model in HT will help us develop accurate models of these circuits byconsidering their architectural description which is based on the opamp model.The work starts with the study of the structure of the SPICE model of the considered opamp.This study enables us to confirm the non-validity of the SPICE model in HT. The validity studyconsists in comparing the SPCE simulation results of two parameters (the voltage offset and thecommon mode rejection ratio) to measurement results. Moreover, we present an interpretation tothe difference that was observed in this comparison. After comparing different modellingapproaches, we select the behavioural modelling one. The VHDL-AMS was used to develop thenew precise opamp model in HT. The simulation is performance in Cadence/ADVanceMSenvironment. The representation of each opamp parameter is validated by a specific circuit. Thismodel is developed in two steps. In the first step, we develop an opamp model in which there is noconsideration of the temperature effect. In the second step, dependence of each parameter to thetemperature is described by a polynomial or exponential function. This function is the result of thefitting process of the measurement results. These equations are inserted in the VHDL-AMS model.All parameters are again validated in each temperature. The test-circuit is the same circuit used inthe experimental test of the opamp parameters. The average error between measurement andsimulation does not exceed 3.11%. In the last chapter, we simulate some circuits of the theanalogue front-end of an acquisition system. We simulate for example the effect of the temperatureeffect on the accuracy of a Wheatstone bridge. Three architecture of an instrumentation amplifierwere also modelled and simulated in different temperature of [20°C, 220°C] in the basis of thedeveloped opamp model
