A Novel Power Conversion System for SMES in Pulsed Power Applications

Abstract

A novel power conversion system (PCS) topology for superconducting magnetic energy storage (SMES) to deliver the required pulses for large, pulsed loads, such as the pulsed magnets of the user facility at Los Alamos National Laboratory, is reported. The simulation results show that SMES, using the PCS topology, delivers the required pulse shape to the pulsed load and recovers the leftover energy back to SMES. The bidirectional DC/DC converter is an innovative approach to achieve high energy transfer efficiency, precise pulse shaping, and efficient energy recovery. The converter eliminates the traditional H-bridge architecture, introducing a more streamlined and efficient design that excels in energy delivery and recovery. The novel PCS system is scalable and efficient for large power loads such as pulsed magnets.
