To brake a 3ph DC, the best I've come up with, apparently, is to place a pair of power FETS, back-to-back across each pair of leads.
I would like to manage a hard short without additional load beyond the motor winding resistance, then duty cycle to get controlled braking.
As far as having the (positive) load current in a NPN MOSFET directed from source to drain, I have only heard of this done once, and that was at low currents.
Is this at all feasible to do this up near the rated current, or am I completely wrong about this?
