🎉We can now proudly present the winners of the TAPAS Community Challenge 2018! 🎉
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 😃 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!

Multipurpose inverter

Inverter to be used in PV applications, motor control, arc soldering, air conditioning, laundry machines, electrical cars and more ... with minor software changes and a modular approach to make minor changes in hardware

    Dear Nora,
    I am sorry I have completely forgotten to write back to you.
    Today when I received the email of the Tapas call I thought of writing back to you.
    Since I do not know too much about the Tapas board, I can not really make a proposal of the exact setup, but as mentioned before my idea is to do a universal variable frequency drive, which changing just external input and output circuits and some software changes we can use the drive as motor controller, photovoltaic panel dc-ac converter, arc soldering converter, in general used as an inverter.

    Power circuits are always needed in the input and the output, the controller board controls the output of signals to power circuits and analyzes signals coming from sensors. In case of motor controller, you have usually an encoder sending signals to the controller, in the case of a PV converter you can control the orientation of panels for maximum output power, in the case of the arc soldering you only need to control output power since there is not much sensing to do except for temperature in the conductors which may not be exceeded, and if we generalize it as an inverter, simply the controller has to give us output signals in different frequencies and voltages in order to obtain the desired effect.
    Hope my idea is clear, I know it is too much to cover, but this is what I have in mind.
    Looking forward to hearing from you. I will try to do some other parts of the design that could be more specific.
    Best regards,
    Diego Eibar.

    Hi Diego,

    thanks for your feedback.
    Our decision deadline is unfortunately reached already so we won't decide on submissions/answers after 1st of June.
    You can of course join our community call to might get some more insights. :-)
