Yes, if we provide a line reactor as a filter to hide the Maxeff generator circuit from the VFD. Using Maxeff on a VFD reduces the possibility of savings on operating costs from 25% down to 8% to 10% max. The VFD will not recognize returning power to the generator. If you are using a VFD only for the purpose of energy savings, you are better off removing the VFD and use Maxeff CMG alone.
