http://www.aliexpress.com/item/10pcs-lot-New-EG8010-LQFP-32-Sine-wave-inverter-chip/32605461001.htmlThe 8010 chip, that has the correct numbers...... 1536 at the end.
I have ordered and they are on the way. ...... we will see.....
6kW-16kW Power Boards..... The only sticking issue at present is the heat sinks, one is 271mm x 80mm x 26mm and the other two are 131mm x 80 x 26. These are coming from China, what we want, and good low cost, but, been nearly 7 weeks now.
These are important as I might need to redesign the mounting positions as the long heat sink makes the big PCB Power Board ridged, important with those 9off 16mm/2 flex cables secured to the heat sinks. Vertical upright mounting can not be beaten for simple heat dissipation and simple fan cooling.
On the Power Boards themselves I have allowed the Solder mask around the FET legs a lot of space for extra solder etc, (straps if needed, but need to test at 15kW, approx 300amps).
The real size board masks that will go with the,
"Making a Low cost, simple and Robust 6kW, 50HZ Pure Sine Wave, 48vdc to 230vac, INVERTER." book as a pull out, will have the option for solder masks as folk might not have the option for double copper thickness on their boards, so will need to beef up the copper.
I will also do the book with the option of also purchasing the bare PCB boards, that's the '6kW-15kW Power Board' and the 'OzControl Board'.
Just finishing the 'OzControl Board'.
'OzControl Board' ....... again Credit where credit is due.
And this Old Fool will need to ask 'oztules' a couple of questions ?.
