TIG inverter -- final gate drive assembly PICTURES

[Ignoramus6826]

That's for my project of adding a DC -> AC inverter to my DC only
welding machine:

bridge:

The above has been tested to generate signal, without the Semikron
boards. The physical configuration was chosen with two goals in mind,
some minor isolation from EMI as well as to fit the welder's
internals. It will be mounted on the heatsink, vertically, next to the
fan.



The inverter bridge is here:

The inverter bridge has been tested with gatedrive "on the bench". The
final assembly was not tested with the bridge yet.



The heatsink and snubber circuit are shown here:
