10 kW
Hi all,
Update - BUILD PICS START ON PAGE 4
I've been toying with this for a little while in my spare time. I think it's time to put it up to see what the experts around here think of the layout and concept.
The plan is for around 3kW, up to 80V max due to component availability. The boards will sit one on top of the other, with vertical interconnects. Currently I am considering my options for the BAT+ and BAT- interconnects. I am thinking standoff posts, but am concerned about their current carry capacity so may just hardware them.
The CPU board sits on top, the driver board and battery buss, with caps is in the middle with FETs and Current sensors on the bottom.
comments welcome. I started on this a while ago, so may have missed some updates to Lebowski's original thread. I don't want to spend money on boards and parts until I have some opinions on the layout. then maybe I'll buy a few boards, and sell them off to anyone keen so I can afford to buy parts.
UPDATED 2015-02-06 This is the file used to produce the PCB's for production / prototype

All of the parts I have chosen from Element 14 Australia. The part numbers are interchangable with Farnell / Newark I think for other countries.
