A loss can be reduced upon a current holding operation of a SMES. A superconducting magnetic energy storage (SMES) system includes a loop composed of a superconducting coil, a thyristor, and a synchronous rectification circuit, and a loop current flow through the loop. In a loop current hold mode, a switching control device of the synchronous rectification circuit turns on the thyristor, and the synchronous rectification circuit compensates for the loop current by rectifying an AC current from an AC power source to generate a DC current.
