The aim of the proposed paper is discussing problematics related to the thermal modelling of power electronic components. More in detail, the electro-thermal relationship is investigated for the selected power diode, while analysis shall serve for system optimization considering thermal performance with the use of highly accurate 3D simulation model. The presented approach describes the procedure of the simulation model development, whereby the main part is discussing necessities relevant for material property identification through the indirect procedure, i.e, material properties are not known from the manufacturer. Electro-thermal dependencies are defined within the proposed model, while this model enables parametric changes of the geometrical properties of the device. Added value of this procedure is the possibility of its use in exact determination of the lifetime of a semiconductor component using mathematical models taking into account operational variables (current, voltage, temperature, etc.). The proposed model is verified and validated through thermovision experimental measurements within defined operational conditions.

“…Over the years, research has been based mainly on the design methodologies proposed by [6,19], proposing changes and optimizing the project according to their acquired knowledge and application requirements [20][21][22][23]. The main difference between these two methods is the output equation used for the SRM.…”

The switched reluctance machine (SRM) has gained much interest in industrial applications, wind power systems, and electric vehicles. This happened because its main disadvantages, such as the ripple in the torque, were overcome due to continuous research and its advantages, such as simple and robust construction, ability to operate at high speeds and variable speeds, insensitivity to high temperatures, and fault tolerance, have made the SRM the right machine for many applications. The SRM project is apparently similar to the traditional machine design, but diverges on several points due to the unique features of the SRM. Over the years, several authors have proposed different project methodologies for SRM, each with its own particularities and often contradicting each other. Thus, for a beginner designer, the SRM project is a challenge from choosing the right design methodology to choosing the values of some dimensions, which are often empirical. This chapter aims to offer the beginner designer a detailed review of the main SRM design methodologies. In addition, an effect analysis will provide useful insights on how each design variable affects machine performance. The designer will thus have important data on which to base his choices during the SRM design.

“…Thanks to their simple stator construction and the absence of magnets and winding in the rotor, SRMs are particularly cheap [1]- [4], robust [2]- [5] and suited for severe environments [5]- [7] and high-speed applications [7]. SRMs also offer a high torque density [3] and very suitable torque-speed characteristics for electrical vehicles (EVs).…”

“…However, SRMs have to cope with some important drawbacks. First, their control strategies are complex, due to the fringing effect and the usually high magnetic saturation level during operation [7], and need a hardware or software position measurement [4], [13]. Second, the need of magnetizing the machine through the phase currents makes SRMs less efficient than permanent-magnet synchronous machines (PMSMs) and higher currents are needed to produce similar torques [5] Third, SRMs suffer from torque ripple and NVH issues [1]- [5], [7], [8], [12], caused by the discontinuous current in the phases [5], and the excitation of structural modes of the machine [8].…”
