Thanks Jerry, no pressure. Much appreciated.

Hi David,

If you are interested, you can give Rhudney Edades a ring at Ayala Materials. He is a one guy shop that will take your docs and get the board built for you. He has arrangements with several CM's in the area from prototypes to high volume runs.

His contact info is rhudney_edades@ayalamaterialservices.com.

Thanks Jerry,

That's very helpful. I definitely give him a call. Smile

Just received version 0.0.2 of the power board PCB; I have all the parts required to build this board. I'm awaiting fully assembled MOSFET driver daughter cards. Should be here any day now. Part of the delay is I trade off delivery date for cost. I could get these boards tomorrow but I don't want to pay the price. Once I receive the daughter cards then I can test the whole enchilada.

Sweet , I will keep my eyes out for non working units David . Thank you for helping to keep these awesome inverters alive .

Today I received my fully assembled MOSFET Driver Boards which are the small boards pictured below. Each of these drives one of the three H-bridges on the Power Board; hence, three per board as shown in the second pic. My next step is to populate the Power Board with MOSFET transistors, a couple of capacitors, resistors, and power cables for final testing.

Looks good Dave!!!

It's getting there Jerry, thanks for the support. I'm looking forward to finishing the power board so I can get back to the software. I'd like to add an IP interface so we can do remote configuration and so we can have non-volatile storage.

IP interface would be awesome!!

I unit tested the Driver Boards. There are four charge pump circuits on each, one for each leg of a given MOSFET H-Bridge, and they all work perfectly. Next, I need to minimally populate a Power Board with MOSFETs so I can test the full build. After that, I'll insert my new assembly into a Trace inverter to examine the output sine waveform.
