Abstract:

The project aims is to extend the research activities in order to develop new methodologies for analysis and optimal design of multilayer spiral inductors used in radiofrequency applications in general, respectively in biomedical applications in particular. In this context, we will approach two research directions: first having the objective to develop, implement and validate a software package for analysis and optimal design of multilayer spiral inductors in high frequency, the APOBSIF Software Package; and the second building of a stand of design, optimization, construction, testing and validation of integrated circuits, the POCT Stand.

At this stand will be practically built the spiral inductors analyzed and optimal designed using the implemented software package, both made on one layer and multilayer. The spiral inductors analyzed and optimized using the APOBSIF software package will be experimentally tested in this stand by specific experimental measurements, thus validating also experimental the implemented software package.Having regard to the extensive applicability aria of the radio frequency integrated circuits containing these spiral inductors is obvious that the approached themes is actual and very important, the research deliverables will have a major impact in the scientific technical, social and economic environments, opening new directions research and further application.

Abstract:

The present proposal answers to two challenges of the electrification of passenger cars: noise-vibration-harshness (NVH) and electromagnetic compatibility (EMC) issues connected to the electrical actuators integration in different subsystems of the vehicle from auxiliaries to powertrain. The thematic of the project is correlated with 7.5.4. (Products and technologies for automotive industry), touching also 7.5.3 (Increasing of safety and security of the transport).

The automotive industry has a continuous high demand for electric drives. The field of actual automotive electric powered units spans a broad range including cooling fans, window and chair actuation, steering, braking, suspension, starter-alternator (integrated or belt driven), HVAC, propulsion for hybrid and full electric vehicles (HEV/EV). The further enhancement of high-performance automotive electric actuation requires energy-efficient, reliable, robust, low-cost electrical machines and highly integrated, energy-efficient power electronics and control modules. For achieving these requirements, the R&D activities should focus on the analysis and development of new topologies and concepts of electrical machines, taking into account the need for energy efficient drives, the harsh automotive environment (high temperature, vibrations, standards for the measurement of pass-by noise, etc.) and the availability of raw materials (in particular rare-earth materials for permanent magnets). Moreover, the integration of electric powered units in vehicles represents an important challenge due to strict and specific noise-vibration-harshness (NVH) and electromagnetic interferences (EMI) requirements.

Therefore, in the context of this new vehicle design paradigm, it becomes critical to understand and manage the interaction between different fields of physics (electromagnetism, thermal, mechanics, acoustics) for the design and development of electrical machines and drives (EMDs) for automotive applications, where both the environment and the specifications are placing more severe restrictions and demands. Moreover, the multi-physics approach should be extended from component- to system-level taking into account the multiple domains that are interconnected and influence each other. The electromagnetic, thermal, mechanical and vibro-acoustic design of the system must be considered simultaneously if the specifications are to be satisfied in the given environment and under specific NVH and EMI requirements. The four designs required for system integration are tightly interconnected and any change in one design will have consequences on the remaining three.

The interdependencies between the electromagnetic design of the most used electrical machines - induction machine (IM), permanent magnet synchronous machine (PMSM) and switched reluctance machine (SRM)- and their thermal and vibro-acoustic behaviour are already under study since several years. However, the generated vibrations are not only an important cause of faults in the driving motor and of annoying noise, but also cause distortions of the controlled excitation current and consequently affect the EMI characteristics at component- and system-level.

In this context, the present proposal unifies knowledge, equipment, and competences in a coupled EMI and vibration analysis in order to identify the key factors in the development of safe electrical actuators for automotive applications and the integration of NVH and EMI issues from the early beginning of their development phase.

The project will approach two new comers in the electric powered automotive units, i.e. switched reluctance machine (SRM) and synchronous reluctance machine (SyRM) and their drives, by comparing their global (torque and efficiency) and specific (NVH and EMI) performances to the ones of permanent magnet synchronous machine (PMSM) drives in order to develop safe automotive electrical actuators.
