Can AC motors be supplied by a dual power supply?
Electrical energy consumers, such as AC motors, can be supplied by a dual power supply consisting of a DC grid and a supercapacitor (SC) energy storage system. The efficiency of energy flow can vary depending on where the energy storage system is connected to the DC network, due to the resistance associated with transmission.

What is a supercapacitor energy storage system (SC ESS)?
In the absence of a reversible rectifier, a bidirectional DC–DC power converter, or a battery as the primary power supply, the energy that is generated by the motor during the braking process can be stored in a supercapacitor energy storage system (SC ESS) .
How efficient is energy flow in SC and DC source dual-supply systems?
The efficiency of energy flow can vary depending on where the energy storage system is connected to the DC network, due to the resistance associated with transmission. This paper details an analysis of energy loss in SC and DC source dual-supply systems based on mathematical and simulation models.
How does a DC-coupled energy storage system work?
