Replacement Trace SW FET Power Board

[davidbrady]

Folks,

I'm developing a replacement power board for our beloved Trace SW4024 pure sinewave inverters. The NOS (new old stock) supply of replacement boards is quickly dwindling. Although the SW has proven to be an incredibly reliable inverter they will inevitably require new parts. Below is a screen capture of the Eagle CAD software package I'm using to model the schematic and layout the printed circuit card. Once I select the components Eagle will generate a Gerber file which I'll then send to a fab house for manufacturing. I imagine having the manufacturer solder the 52 FETs and assorted support components. I'll then finish the assembly which includes soldering heavy gauge AC and DC power cables, and bus bars. I still need to develop the MOSFET driver cards and test everything.
