An analytical evaluation of rotor eccentricity effects on synchronous drives with surface mounted permanent magnet brushless motors

Emanuele Fedele - Università degli Studi di Napoli Federico II, Italy

PRESENTATION

An analytical evaluation of rotor eccentricity effects on synchronous drives with surface mounted permanent magnet brushless motors

ABSTRACT

The paper deals with static eccentricity in synchronous PM motors with surface mounted magnets. Simple analytical expressions are proposed for the evaluation of the length of stator and rotor magnetic field lines in the airgap as a function of rotor eccentricity. By means of some appropriate considerations, the analytical expressions of the flux-density distribution of armature and rotor across the airgap is yield. They allow us to point out a mathematical model of the machine in terms of concentrated parameters. The model is then used in order to evaluate the variations that can occur in the armature currents or in some characteristic parameters of the machine in steady-state operating conditions, with respect to the case without eccentricity.

Performance Comparison of modified modulation Techniques for Quasi-Z-Source Converters

Giuseppe Schettino - University of Studies of Palermo, Italy

PRESENTATION

Performance Comparison of modified modulation Techniques for Quasi-Z-Source Converters

ABSTRACT

The single-stage converters represent an innovation in the field of power electronics thanks their features. Aim of this work consists in the improvement of the performances of quasi-ZSource converters by adopting a modified modulation technique, which is based on the Maximum Constant Boost Control (MCBC) and Switching Frequency Optimal (SFO). The results in terms of voltage stress and harmonic content are compared with those obtained with conventional techniques, demonstrating the effectiveness of the proposed modulation scheme.

Modelling, simulation and characterization of a supercapacitor

Vincenzo Junior Castiglia - University of Palermo, Italy

PRESENTATION

Modelling, simulation and characterization of a supercapacitor

ABSTRACT

In the last decade, the issue of air pollution or the reduction of CO2 emissions has become of extreme interest both for civil society and then for the industrial and scientific research world. For this reason, the scientific research on automotive is called to answer with increasingly innovative solutions. One of the principal subjects are the storage and the utilization of the electric energy for electrical and hybrid vehicles. Nowadays, supercapacitors are getting more and more attention because of their characteristics that allow them to be a bridge between electrolytic capacitors and batteries in several application such as bust-mode energy delivery, regenerative breaks and so on. The aim of this work is the modelling, simulation and characterization of a supercapacitor for the seen automotive applications.

A prototypal PCB board for the EMI characterization of SiC-based innovative switching devices

Filippo Pellitteri - University of Palermo, Italy

PRESENTATION

A prototypal PCB board for the EMI characterization of SiC-based innovative switching devices

ABSTRACT

In this paper, a preliminary PCB board for the electromagnetic interference (EMI) characterization of innovative silicon-carbide (SiC) based switching devices is presented. Packaging technological issues can determine hurdles in the high-frequency switching and high power regime where wide band gap semiconductors are intended today for Electric Vehicle (EV) applications. In particular, the parasitic inductances that emerge in such devices, must be assessed, by using e.g. EMI techniques. In this specific case, the EMI characterization is supposed to be carried out in a semi-anechoic chamber, available at the University of Palermo (UNIPA), to assess the electromagnetic disturbances according to the levels of compliance indicated by the standards. The proposed prototype can work properly at the following levels of voltage, frequency and load power: 28.5 V, 2 MHz and 40 W. Details concerning the layout design and the prototype manufacturing are discussed.

A Low Cost Programmable Hardware for Online Spectroscopy of Lithium Batteries

Luca Pugi - University of Florence, Italy

PRESENTATION

A Low Cost Programmable Hardware for Online Spectroscopy of Lithium Batteries

ABSTRACT

In this work, authors present an innovative low cost hardware for online spectroscopic analysis of lithium based accumulators. Proposed system designed on a TI development board that can be easily programmed using a Matlab-Simulink™ Target Compiler that can be also easily used both for research or teaching activities. Additional interfaces are provided by cheap programmable shield boards of easy usage being programmable using the Arduino IDE™. Proposed System has been successfully assembled and tested at University of Florence on a benchmark test cell. Work is focused on the description of the proposed systems and on the design of an innovative identification procedure, which is verified also experimentally.
