John Metric posted that on FB recently

The design look really nice with these 3 circles of Fets around each of the 3 phase...!

Is this a controller for an electric Motorhome?

Pah, a mere 0.36MW...

Surely not FETs at 800V?

Why not?

Look at how low their IR is for their voltage.

Those circles are 3 capacitors. The IGBT modules are on the right under the busbars and PCBs. Similiar to what the PM100 controllers looked like. Use to have one of those and took a peak inside
