EVs in 1910

"Electricity is the thing. There are no whirring and grinding gears with their numerous levers to confuse, no dangerous and evil-smelling gasoline and no noise."
- Thomas Edison

Ensuring Long-term Success through Innovation and Entrepreneurship

Forward thinking solar manufacturing and service companies understand that they must leverage the current domestic market opportunity and incentives to create a robust export market. This requires the sector to identify its strengths, predict market directions, find the matches between the two and respond with high value-added technologies, products and services to win these markets over.

Where is the global solar market evolving? What promising technologies and services are being developed in Ontario? How might the necessary innovation and entrepreneurship capacity be fostered? What supports are available (or required) to make this a reality? This session is a must see for companies interested in ensuring their competitiveness and growth in the medium to long term.

IEEE Spectrum Webinar - UofT - NI - NREL

Accelerating Development of Smart Grid Power Electronics Control Systems with RCP and HIL Techniques
The design and deployment of grid-tied power electronics control systems historically has been hampered by a lack of rapid prototyping, commercial off-the-shelf embedded systems and real-time HIL simulators that satisfy the demanding requirements of switch-mode power system designers. To address these challenges, National Instruments is involved in a collaborative R&D effort with the National Renewable Energy Lab and other groups to develop a comprehensive new tool chain for power electronics system design based on reconfigurable FPGAs and high level graphical programming tools. Attend this session to see live demonstrations of new hardware/software tools under development and information on how you can become pioneer user and collaborator in the effort.
