Abstract
A pulsed transformer having a superconducting primary winding and a normal conducting secondary winding. The secondary winding is connected across a load. One side of the secondary winding has a switch in series to the load. A high energy storage inductor is connected in parallel across the switch. With the switch closed and the primary winding and storage inductor charged to their maximum capacity, a high level of current now flows through the switch. The primary is then caused to go into its normal conducting mode collapsing the primary field which induces current into the secondary winding. As the secondary winding current increases the high level of current normally flowing through the switch decreases to substantially zero. When the switch current reaches substantially zero, the switch can be opened without damage thereto releasing the high energy from the storage inductor into the load. The switch primary winding can be constructed from a high temperature superconductor for improved performance.
