A persistent switch control system, a superconducting magnet apparatus employing the persistent switch control system, and a method of controlling a persistent switch. The persistent switch control system includes: a persistent switch for switching between an open state and a closed state of a superconducting coil; and a persistent switch controller for controlling the persistent switch, wherein, during a charging mode, a resistance state of the persistent switch is maintained by a ramp heat load that is generated by a ramp voltage applied to the persistent switch.
