Abstract
Abstract A device for rapidly transferring energy from a superconductive storage device to a utilization device. A first switch is coupled across the superconductive device and a second switch is coupled across a secondary of a transformer comprising the superconductive device and the secondary. The utilization device is coupled across the secondary in parallel with the second switch.
