Reliable and Flexible Switching System

[dancombine]

Chris, MarkE,


The design I have was improved over the years and is very stable. I made several prototypes and versions, and works now very well.
here's a picture of v5 of the board: http://users.skynet.be/fc372083/public/boards/2014-05-29%2009.32.37.jpg

Since then I made some minor adjustments and the board is now called IPC-quadra v6.
The changes are mostly some small layout changes (not related to the core of the isolated power switching), and make it universally usuable to interface with any control board (Arduino, Beaglebone, etc.)
The specs are:
- 1kV galvanically isolated for control signals
- 1kV galvanically isolated between all 4 power channels (as such user is flexible on how to connect those together, either H-bridge, push-pull, etc...)
- control signals 3 - 5V compatible
- power section: max 600V & 4A (10A with re-enforced copper traces by soldering) (so 6kVA reachable, and tested in vitro as such)
- operating frequency: DC to 1MHz (depending on choosen power transistor)




I'm willing to make a batch of 25 such boards, if there would be enough people interested.


Regards,

Dan, maybe the thing for you to do is publish specifications and then do an IndieGoGo or Kickstarter campaign to cover your internal cost for 25 - 100 boards and something for your time.  If the campaign fully funds then you can offer to sell the boards for what you think is a reasonable price.

Hi MarkE,


yes I've been thinking about a Kickstarter project.
The practical drawback for you guys is that this will take time before boards can be available.


If there is a small community of 25 interested, I can start a small batch quickly, and later move to a larger Kickstarted based volume.

Dan, you are being generous by taking such a risk on people's say so.  In your shoes I would collect enough deposits first to at least cover the fixed costs.  Essentially you could set-up KickStarter to do that.

Ok Guys,

Please let us know who is interested! See attached File. No PLL, No Microcontroller, this is bare board with Components Soldered and ready for you to plug in your gear.

Price coming tomorrow when confirmed.

All the Best
