Topic:

Fiber optic temperature sensing for the power industry

Fiber optic temperature sensing was first commercialized about 30 years ago, but until recently it has seen limited adoption in the power industry.  Today, new advancements have made fiber optic temperature sensing much more affordable and opened the possibility to use this technology in places where high voltage or electrical noise make traditional wired temperature sensors impractical.  In the power industry, fiber optic temperature sensors are now installed in low and medium voltage switch gear, transformers, generators, transmission cables, and elsewhere.  Osensa Innovations develops, and markets so called “end-point” fiberoptic temperature sensors for these markets.  This presentation will include an overview of competing fiber optic temperature sensing technologies and discuss how these different technologies have been deployed in various applications.  It will also include a hands-on demonstration of Osensa’s fiber optic temperature sensor products.

Biography:

Daryl James founded Osensa Innovations Corp. in 2010, after spending over fifteen years developing optical technology products for local high-tech companies.  Mr. James has a strong technical background in precision opto-mechanical systems, and is named as an inventor on a number of patents. Mr. James enjoys solving complex technical challenges by seeking the simplest solution and shortest path to success. This philosophy carries over into the way he manages OSENSA, in a very straightforward, lean and disciplined fashion. His passion for technology and business innovation allow him to create value and find opportunities in a wide range of markets.

Topic:

Thermal Characterization of Power Electronic Devices

In order to power and operate electronic devices such as laptops, cell phones and electric vehicles, different power conversion circuits are necessary. These rely on power electronic components, which, even though highly efficient, still produce heat due to power losses. In order to allow for proper operation, adequate thermal management techniques are required for cooling these devices, which often operate at frequencies of hundreds of kilohertz. The measurement of the dissipated power of these devices to determine the best thermal management approach, can be realized with different techniques, ranging from electrical measurements to calorimetric approaches. An overview of the known technologies and processes for power loss measurement is presented, along with their analysis when applied to high-frequency switching components. In addition, a thermal method for estimating losses in a single device is presented, which allows for the assessment and design of an appropriate thermal management in power electronics switches.

Biography:

Ettore Scabeni Glitz was born in Curitiba, Brazil, and he received his Bachelor of Engineering degree from the Federal University of Technology in Parana, Brazil in 2016. He is currently a student in the Master of Applied Science in Electrical and Computer Engineering at the University of British Columbia in Vancouver, Canada. His research consists on the analysis of power losses in active components for power electronics topologies, focusing on the behaviour of the LLC resonant converter. Mr. Scabeni Glitz has been a recipient of a number of awards and scholarships during his studies, including the Science without Borders scholarship from the Brazilian government and the technical session presentation award from the IEEE Applied Power Electronics Conference and Exposition. Mr. Scabeni Glitz is also one of the inventors of a technology for pressure sensing based on the electrical signal generated by mobile ions in a piezoionic layer.

Maria Celeste Garcia Perez obtained her Ingeniera degree in Electronic Engineering at the National University of Comahue in Neuquén, Argentina. She is currently pursuing a Master in Applied Science in Electrical and Computer Engineering at the University of British Columbia. Her research interests include modeling and characterization of switch mode power electronic converters employing advanced device technologies such as Silicon-Carbide and Gallium-Nitride.

Matt Amyotte received his Bachelor of Science in Engineering Physics from the University of Alberta in Edmonton, Alberta in 2013. Following nearly 3 years of work experience in the oil and gas industry, he decided to shift his career focus to renewable energy and sustainable technology. This led him to return to academia to pursue his Master of Applied Science in Electrical and Computer Engineering at the University of British Columbia in Vancouver, Canada. His research interests focus on characterization of wide bandgap devices and their applications in new high-efficiency topologies. Mr. Amyotte has been a recipient of a number of awards and scholarships, including the APEGA Past Presidents' Medal in Engineering Physics as the top engineering physics graduate, and the NSERC Alexander Graham Bell Canada Graduate Scholarship.
