Replacement Trace SW FET Power Board

RE: Replacement Trace SW FET Power Board
These boards measure 14"x3.5" and they contain the 52 MOSFETS that form the three H-bridges that power the transformers in inverting, 24VDC to 120VAC, and in converting, 120VAC to 24VDC. There's one board per SW4024.

You are on your way, is the new board the same size as the existing board in the SW4024?

RE: Replacement Trace SW FET Power Board
Hi Hish,

It is identical in size. I mentioned there are 3 driver cards that drive the 3 H-bridges. I sent them off for PCB fab too. I expect to get them back this coming week, then I can solder on some components and test the entire assembly. The boards were $33 each, but that's for 1 ounce copper, which is suitable for low power testing, but for the final 4KW device I'll need 4 oz PCBs for the PowerBoards, and 3oz for the driver cards. I'll have to order around 15 of them to keep the per board cost down, so I want to do as much test as possible with the cheap $33 each 1 once PCBs. It's exciting to get the boards. I'm looking forward to populating them and plugging them in! It's taken a while because I spent a bunch of time on the software side.

This would be good think to have to keep these great inverters run. As it is now if this board is dead you have a boat anchor for an inverter. Good job David

RE: Replacement Trace SW FET Power Board
This week I received my three Driver Board PCB's. $33 each. There's three MOSFET H-Bridge's on the Power Board and each H-Bridge get's it's own Driver Board. Now the fun part of soldering on a ton of components and low power testing; basically, testing waveforms.
