“…As for energy storage systems (ESSs), one option is to use a Superconducting Magnetic Energy Storage (SMES) system, as they have much higher power density than batteries, supercapacitors, etc., faster response times in milliseconds, very long operational lifetimes, high cycle life, and can satisfy large pulse loads, though its disadvantages include higher cost per kW, relatively high parasitic losses (mostly from using power switches for the chopper circuit), and the obvious need for constant cryogenic cooling [9]- [11].…”

“…While current literature has separately explored using DAB converters for different loads [3]- [6] and some ESSs [8], and SMES integration into systems (terrestrial grids via chopper or hybrid solution for EA) [9]- [11], none have tried to combine both for EA. This paper proposes a methodology to design and control a combined DAB/SMES system for use in EA, presents its operation using the PLECS simulation platform, discusses its implementation, and uses simulations to predict its performance.…”

High-density power conversion and energy storage solutions were and are being explored for use in Electric Aircraft (EA). A superconducting magnetic energy storage (SMES) system is a promising candidate due to its fast response and ability to satisfy large pulse loads as is expected from EA. For the SMES, Dual Active Bridge (DAB) converters can offer high-density power conversion and provide galvanic isolation. This paper proposes a design methodology for a bidirectional DC/DC converter using DAB converter and a MOSFET-based chopper to interface SMES. This paper includes analysis, performance prediction, and needs for implementation in EA. The DAB/SMES system has been successfully designed, analyzed, and is being optimized for application in EA.
