Thursday, August 9th at 11:00 a.m., the IEEE Toronto Section, Consumer Electronics Chapter invites you to the IEEE CESoc Distinguished Lecture on: “Convergence between Broadcast and Mobile Broadband” by Dr. Ulrich Reimers, IEEE CESoc Renowned Distinguished Speaker, and Professor Institut fuer Nachrichtentechnik (IfN), Technische Universitaet Braunschweig, Germany. Day & Time: Thursday, August 9, 2018 11:00 a.m. ‐ 12:00 p.m. Speaker: Dr. Ulrich Reimers IEEE CESoc Renowned Distinguished Speaker Professor Institut fuer Nachrichtentechnik (IfN), Technische Universitaet Braunschweig, Germany Location: 40 St George Street Toronto, Ontario Canada M5S 2E4 Building: Bahen Centre for Information Technology Room Number: BA7180 Contact: Mahdieh Taghizadeh Organizer: IEEE Toronto Section, Consumer Electronics Chapter RVSP: https://events.vtools.ieee.org/m/174204 Abstract: The mobile industry has been testing the feasibility of evolved Multimedia Broadcast Multicast Service (eMBMS), an LTE embedded broadcast approach to support a growing mobile video/TV consumption and the delivery of other highly popular data services. But, eMBMS has so far only been used in small scale scenarios with local coverage. When it comes to large scale service areas with regional or even national coverage, the cellular nature of eMBMS has not proven to be attractive for cost efficient LTE broadcast content distribution. Adapting LTE broadcast to traditional High Tower High Power (HTHP) broadcasting towers and introducing this as a third service layer, i.e. as an extension of LTE unicast and eMBMS can resolve this issue as it reduces network load, energy consumption and network costs for such popular services. Additionally, it creates the possibility of cooperation between the cellular and broadcasting networks enabling a cooperative spectrum usage. The term “Tower Overlay over LTE-Advanced+ (TOoL+)” describes the transmission of an extension of LTE-Advanced (LTE-A) offering broadcast services, especially live video, from a traditional High Tower High Power (HTHP) broadcast infrastructure, rather than in a cellular LTE-A network. TOoL+ was invented and developed by IfN. Since LTE-A is optimized for the Low Tower Low Power (LTLP) environment of cellular networks, the use of a HTHP environment requires some modifications of the LTE-A standard, e.g. the definition of a dedicated broadcast carrier and of additional OFDM parameters with longer cyclic prefixes. These modifications are represented by the term LTE-A+. In one of the modes, TOoL+ even supports a cooperative spectrum use by DVB-T2 (or ATSC 3.0 in the future) and LTE-A+ if this is attractive to market players. IfN developed a Software Defined Radio (SDR) based TOoL+ implementation to demonstrate the technological feasibility of this approach. An extended version of this demo has been used during two field trials conducted in Paris, France and in the Aosta Valley, Italy to evaluate the proposed modifications and the cooperative spectrum use in a real environment. The analysis shows that LTE-A+ is a suitable technology for HTHP broadcast to mobile devices as its coverage area is similar to that of DVB-T2. In line with the ideas underlying TOoL+, 3GPP has recently specified FeMBMS (Further evolved Multimedia Broadcast Multicast Service) in Release 14. FeMBMS supports a long cyclic prefix and thus makes larger network cells feasible. At IfN we have already implemented FeMBMS and by the time of the lectures in Canada will have carried out a field trial in at least one European country. Biography: Prof. Ulrich H.

Friday, October 12th 2018, Sudip K. Mazumder of University of Illinois at Chicago, will be presenting “Control of Power Electronics Systems Using Predictive Switching Sequences and Switching Transitions”. Day & Time: Friday October 12th, 2018 4:00 p.m. ‐ 5:00 p.m. Speaker: Sudip K. Mazumder Professor at the University of Illinois at Chicago Organizers: IEEE Toronto Power Electronics Chapter Location: Room Number: BA 4287 Building: Bahen Centre for Information Technology University of Toronto 40 St. George Street Toronto, ON M5S2E4 Contact: Mahdieh Taghizadeh RVSP: https://events.vtools.ieee.org/m/176071 Abstract: This presentation provides a fundamentally different perspective to the control of solid-state semiconductor-device-based switching power-electronic systems (PESs). It is based on controlling the time evolution of the feasible switching sequences and controlling the switching transitions of PESs. The former – that is, the switching-sequence-based control (SBC) – yields rapid response under transient condition, optimal equilibrium response, and yields seamless transition between the two dynamical modes. Further, by enabling integration of modulation and control, SBC precludes the need for ad-hoc offline modulation synthesis. In other words, an optimal switching sequence for a PES is generated dynamically without the need for prior determination of a modulation scheme (which generates a pre-determined switching sequence) as evident in most conventional approaches. This presentation will provide the mechanism to carry out SBC synthesis and how it leads to multi-scale optimality leading to enhanced PES performance. Subsequent to the outline of SBC, the presentation will focus on switching-transition control (STC). The primary objective of STC is to demonstrate how key PES parameters including and stress, switching loss, electromagnetic noise emission can be controlled dynamically by modulating the dynamics of the power semiconductor devices. Both electrical and newly developed optical-control mechanisms to achieve STC will be briefly outlined. Finally, envisioned mechanism for monolithic integration of SBC and STC will be illustrated. This presentation will demonstrate, along with results, multiple practical applications (currently of high priority in the power/energy space) where the radically new control concepts make a tangible and substantive difference.

On Wednesday, September 2, 2020 at 1:00 p.m., Frédéric Mathieu from Bender Canada will present “Electrical safety, Ground Fault monitoring for Electric Vehicles and Charging Stations”. Day & Time: Wednesday, September 2, 2020 1:00 p.m. – 2:00 p.m. Speaker: Frédéric Mathieu, Sales Manager & Head of EV Division (Canada Region) at Bender Canada Organizers: IEEE Toronto Power Electronics and Consumer Electronics Chapter and Bender Canada Location: Virtual Contact: Mostafa Mahfouz Abstract: As more electric vehicles and charging stations are in operation in the world, the importance on electrical safety should not be overlooked. Electric vehicles and charging stations are prone to electrical failures just as much as industrial-type electrical systems. One of the most fundamental aspects of electrical safety is Ground Fault monitoring and protection. This talk explores the different protection mechanisms used for ground fault detection on EV and EVSE and the product solutions tailored for the environments of electric vehicle and its charging process, in particular the mix of AC and DC within the same system. Accurate and reliable insulation monitoring inside the EV ensures the electric vehicle is safe to use for its occupants. In addition, many electrical codes and standards regulate electrical safety in charging stations, and this talk will focus on Residual Current monitoring for Level 2 chargers and Insulation monitoring for Level 3 chargers.

He has worked with many major utilities companies, OEM and end users to assist in applying ground fault monitoring to maximize electrical safety on their systems.

Reliability is a main design prerequisite in public transportation systems. This talk will address the governing parameters for a successful reliable propulsion system. Also, the system is not only required to be reliable but most importantly safe. Those considerations will highlight the power electronics' components design. The talk will address how to combine safety and reliability into the design phase of any propulsion system. A case study will present the propulsion design of the Light Rail Transit (LRT) Vehicles. All pertaining design requirements will be verified towards the welfare of a successful deployment of the LRT project in Toronto.
