There's actually a clever way to reconfigure the inverter electronics and (induction) motor to essentially do "regenerative braking" off of a 3-phase supply (https://patents.google.com/patent/US5341075A/en https://patents.google.com/patent/US5341075A/en). I'm not sure if this is so widely used as to not be worth mentioning, or if there are hidden gotchas or patent encumbrances that keep it from being widely used.
