ūüéČWe can now proudly present the winners of the TAPAS Community Challenge 2018! ūüéČ
Congratulations to Team "Wireless Charging" (idea 56). We are really excited for all finalists and a really big thank you to all participants for your interest in this challenge!

We got over 200 submissions! 65 ideas got one or more TAPAS boards, 10 submissions were presentation-ready.
And now we have 5 finalists! YEAH ūüėÉ The finalist's idea numbers were 40, 56, 68, 212 and 213.
What's next?
We are now preparing the next steps for you, the community. Please stay tuned!
We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!

Plug-and-play logic stage for E-Mobility applications in any scale and Smart Cities integration

I would like to evaluate new semiconductors based on GaN for use in High Power Mobile Inverters.

By creating only one platform (logic board) for every e-driven vehicle (ebike, small car, motorcycle, etc.)  and scaling the power section, the E-mobility could get more standardized, which would cut down the costs for infrastructure in a "smart city" , i.e.  using motor inductance and the semiconductors backwards as a boost/buck converter would reduce the costs of charging stations.

Therefor I'd like to build a plug-and-play solution based on the TAPAS BOARD. Plug-and-play because the logic part (TAPAS BOARD) can be plug onto any high power Mosfet/IGBT/GaN/SiC Stage.

    This idea will get a TAPAS dev kit.

    Could you provide some more detail how such a logic board would look like?

    The power stage would be exchangeable. I think a modular design is the best way to go. Basically it should get as easy as switching a Arduino-shield (a PCB that can directly be mounted on top of the Arduino ¬ĶC Board).

    So the logic board gets a predefined size and a basic board layout for the power stage will be provied.

    Developers can start their project on top of the "shield layout". The logic part will be based on the TAPAS board without the mosfets, which will then be part of the individual shield.

    That's one of the possible implementations. Additionally a website can be provided where a graphical configuration will be possible. A developer can select a logic board (maybe interesting if other revisions of the TAPAS Board are released) and a power board (provided by the community and saved in a database or the dev can upload his/her own design based on the TAPAS-shield) so the software can generate all .h files or do some electrical checks on the schematics.


    All in all this would spread the TAPAS Board as it would get an universal solution for every inverter needs.

    Additionally a community could provide ready to use solutions, so not every power requirement to an inverter has to be designed from the start each and every time.

    I think i missed something in my explenation. The structure of the project would be:
    1. TAPAS Board including an onboard powerfull MCU (i.e. ARM) for advanced standalone operation, Gatedrivers, BUS Systems (CAN, SPI, ...) for sensors

    2. Power Stage, containing only the semiconductors (GaN, SiC, ...) and userspecific additions (sensors, gate resistors, ...)

    3. Web Application for configuration of the inverter system

    Great idea! Our TAPAS team will contact you regarding a free TAPAS board shortly.

    Hey Max,

    Please keep in mind that the submission deadline for your presentation is on 24th of June! We are already looking forward to seeing how you brought the TAPAS board to life! :-) Remember that you still have time to work on the implementation of your idea after the submission!

    Please upload your presentation and everything you want to share with us in your idea board entry.

    Good luck :-)

    Jacqueline @ TAPAS Team
