This is the hardware repository of a 3 phase inverter, UNTESTED but designed with the following specs in mind:
- 70kw nominal, 150kw peak
- TO247 IGBT to allow for easy silicon upgrades and power capabilities. Its also cheaper.
- Watercooled
- Embedded security features (desaturation, soft turn off, reinforced isolation)

Will need some cnc milling, components, a pcb, and some spot welding
Made open source with open source tools (kicad, freecad)
BOM, pcb gerbers, and custom parts can be found in fabrication files directory
