Replacement Trace SW FET Power Board

[davidbrady]

Hi Prodriver,

Thanks for your support. There's one power board in each inverter which drives the three transformers. On each power board there are three MOSFET H-bridges, one H-bridge for each transformer. It really is three inverters in one. This is why it's an expensive design compared to todays high frequency inverters, and most likely why Xantrex obsoleted it. In part, because the high frequency inverters lack the Trace's magnetics (transformers), they don't have the grunt to start heavy loads.
