A couple of years ago I saw a contraption at a trade show where someone had coupled a regenerative AC drive to a flyweel to provide voltage ride through on dips. I think it was at the power quality show in Chicago.
Any help is appreciated.
Using the inertia of a flywheel in the middle of an m-g set for temporary energy storage is an old but good trick. Coupling it with a power exit inverter for constant frequency UPS output gives a useful twist. 1 posts 2. Thanks for your answer. Top Perry Conte 2 posts 5.
