This thread is for a power section that is designed to work with the processor board described in this thread:

The basic idea is to have an easy to solder PCB with a connector for Bob's board. The power PCB will have a simple low inductance bus bar setup, 6 TO247 FETs, gate drivers (using IRS 2186) and current sensors (ACS 770 type). The goal is to have the board complete, so with no hand wiring necessary.
[pre]
Recommended gate resistors and deadtime for popular FET types:
FET R_off [Ohm] R_on [Ohm] deadtime [nsec]
--------------------------------------------------------
IRFB4468 4.7 15+4.7 600
IXTH180 15 47+15 500[/pre]
This is the database for the 'jan 2018' version:

For reference, measurement pictures for different R_on and R_off:
