Reliabilty and failure analysis of Wide Bandgap power transistors: application for telecommunication systems and power convertors.

Prof. Pascal Dherbécourt, Institute of Technology in University of Rouen – Normandie, France :

Abstract : Responding to the current economic requirements, the new power transistor technologies as SiC (Silicon Carbide) and GaN (Gallium Nitride), are now available on the market. They offer increased performance compared to traditional silicon components, in terms of voltage withstand, high temperature operating. Applications such as PFC/power supplies and photovoltaic inverters, electric vehicles, rail and others are now contributing to the growth of the SiC and GaN market. HEMT GaN transistors are also deployed for high power microwave applications, and find their interest in telecommunication and radar systems. GaN technology is essential thanks to the intrinsic properties of the material, in particular the high electronic mobility. However, the lack of experience feedback on these technologies encourages industrials and academic researchers to study, through collaborative research projects, their reliability and degradation of performance in operational conditions. We present the context and the problematic of the reliability and failure analysis study of power transistors, the general methodology developed within academic research and industrials partners meeting the defined objectives. Several examples of studies carried out, particularly concerning the MOSFET SiC, then HEMT-GaN power transistors, are described.

Multi-Heat Sources Silicon-Die Thermal Monitoring Using Embedded Sensor Cells Unit: Challenges and Methodology for thermal peaks detection.

Prof. Ahmed Lakhssassi, Quebec University, Outaouais, Canada:

Abstract : Nowadays, real-time thermal monitoring is essential in integrated circuit (IC) and VLSI chip which are a multilayer structure and a stack of different materials. The evolution of the integrated circuits industry (IC) during the decade has been so rapid that it is possible to integrate complex systems on a single chip (SOC, system on Chip). This trend towards increasingly high levels of integration is driven by the need for increasingly efficient systems and thus dissipating enormous power densities. Currently researchers have already designed an algorithm for detecting thermal peaks in the case of a single heat source based on the GDS (Gradient Direction Sensors) methodology. However, this does not solve the problem of thermal peaks monitoring in LAIC (Large Area Integrated Circuits) circuits. In this paper we presents an algorithmic and the experimental result of multi-sources silicon-die thermal monitoring method using embedded sensor cells unit. The methodology that has been used is based on the generalized GDS methodology for the case of multiple heat sources. The test results of a configuration of embedded four (4) GDS sensor cells unit has been proposed for the detection of thermal peaks in the case of multiple sources. Our results shows that our algorithmic solution give a satisfactory thermal peak prediction with less than 1.2 % error.

UNDERSTANDING THE BENEFITS OF MIMO RADAR TECHNOLOGY.

Prof. Mostafa Hefnawi, Royal Military College (RMCC), Canada:

The application of multiple-input multiple-output (MIMO) techniques to radar systems has received considerable attention recently. Unlike traditional phased-array radars in which a steered beam is used at the transmitter to scan a sector, MIMO radar transmits different waveforms from each omnidirectional antenna element simultaneously, allowing for a sector scan rate that is several times faster than steered beam radars. The waveforms with the target information can be extracted by a bank of matched filters at the receiver end. Generally, MIMO radar is implemented through either widely separated antennas or through colocated antennas using orthogonal independently transmitted waveforms. In a MIMO radar with widely separated antennas, each transmit-receive pair sees a different aspect of the target, which improves the detection probabilities of targets. This configuration relies on space diversity to improve the detection performance but does not provide the flexibility of transmitting the desired beampattern. On the other hand, in a MIMO radar with collocated antennas, the antenna elements are closely spaced so that each transmit-receive pair sees the same aspect of the target. In this talk, the potential benefits of MIMO radar and comparisons with conventional radars, will be investigated.

Development of bio-inspired antennas for high voltage equipment monitoring.

Prof. Alexandre Jean René Serres, The Federal University of Campina Grande, Brazil :

The increased demand for quality energy, generated by population growth and the dependence of modern society on electrical/electronic devices, results in the demand for increasingly reliable energy generation, transmission and distribution systems. This characteristic can be obtained from the elaboration of systems: redundant with adequate protection philosophies; with maintenance of energy quality indices and; with the application of predictive monitoring on the equipment that composes them, such as power transformers, circuit breakers, insulators, instrument transformers and others. These high voltage equipment are subject to various stress conditions due to intense electrical fields, chemical reactions, mechanical stresses, temperature variations and environmental phenomena to which they are subjected daily during their operation, resulting in failures. The radiometric method stands out as one of the most promising methods for monitoring these equipments. In this talk, the development of bioinspired shape antennas applied in high voltage equipment will be presented.

Empowering Energy Trading Users in the Smart Grid with Blockchain-based Systems and Intelligent Strategies.

Prof. Abdulsalam Yassine Associate Professor and Chair of the Software Engineering Department at Lakehead University, Thunder Bay, Ontario, Canada. :

Energy trading allows smart grid-connected parties to exchange energy among each other. Various schemes such as Vehicle-to-Vehicle (V2V), Vehicle to Building(V2B), Vehicle-to-grid (V2G), etc. allow users to receive monetary rewards while at the same time help to alleviate the imbalances between the supply and demand during peak hours. However, energy trading schemes face challenges and bottlenecks. First, lack of a secure, private, and transparent system to stimulate users to participate in the energy trading systems. Second, energy trading models require autonomous intelligent mechanisms that foster optimal strategies for users to take the most favorable energy transactions at a certain time of day to maximize their economic benefits. Such intelligent mechanisms require continuous learning to evolve with the changing environments. The first challenge can be tackled with blockchain technology, which permit users to store their state of energy supply/demand as assets that are immune to tampering and enhance security, privacy, and transparency. The second challenge can be addressed with artificial intelligence mechanisms and cooperative gaming that help users to build strategies to maximize on their trading decisions. This talk introduces the concept of energy trading, blockchain and its application in the domain, as well as examples from current research.
