“…It determines the position of the accelerator pedal which allows to track a desired speed. Moreover, the power converters connected to the electric actuators have been optimized under thermal, electromagnetic compatibility (EMC) and efficiency constraints [15], [16], [17]. A vehicle starting test is carried out to validate the modeling of the equivalent transmission chain.…”

This paper presents a vehicle transmission simulator coupled to a longitudinal vehicle dynamic model. The transmission simulator uses electric actuators to reproduce the mechanical characteristics of a real vehicle engine and its transmission chain. The developed approach allows to validate transmission and vehicle dynamic studies (control of automatic or robotized gearboxes, test of heat engine, dynamic behavior and passenger comfort…) without need to the real transmission system and the real environment of the vehicle. The proposed system is used to carry out a vehicle automated driving in the case of a car-following operation.

“…An equivalent frequency is derived for the arbitrary waveform to be used with the basic equation and the effects of temperature are also considered. In [46][47][48], a generalisation of Steinmetz equation based on [49], which seeks to calculate core losses in discontinuous (DCM) and continuous (CCM) conduction modes for a buck converter, is used. In these calculations, core losses in DCM depend only on frequency and maximum flux density while they depend on frequency, maximum flux density and flux density changes in CCM.…”

Design optimisation techniques for power electronic converters have been the subject of numerous research studies for the past 15 years. Accurate modelling is the most important task in the optimisation, and, because the nature of optimisation problem demands evaluating an objective function numerous times, fast and simplified modelling techniques are required. The objective of this study is to categorise and analyse the previous studies related to modelling techniques incorporated in design optimisation of power electronic converters. Common trends in modelling and optimisation of power electronic converters are analysed and suggestions for future research in this field will be presented.

“…However in the same time, other constraints must be fulfilled: external requirements obviously, but also other technological parameters, such as maximum losses in the components, or peak voltage on the semiconductors… Last, if a maximal height is required, component choice must account for this geometrical constraint. This paper has thus the same goal as other design procedures explained in [1][2]. However, the proposed method does not rely on complex computer aided methods, as expert systems or heavy time simulation.…”

Abstract-This paper gives generic formulas to account for power components surface in the design of a flyback converter. Starting from the converter requirements, key design parameters are defined, and their influence on converter surface studied. It is shown that some parameters have opposite actions, thus some trade-off must be found. On the other hand, additional constraints must be taken into account, especially losses. These ones are also evaluated using analytic formulas, and included in the design procedure. After design, the converter has been built, and compared to previous version, surface reduction is obvious.
