Abstract

An improved SMES circuit topology is proposed for improving the energy storage and discharge efficiencies. The switching control principle of the improved SMES circuit topology is presented in detail with an experimental HTS coil switching control system designed. The results obtained verify that the control system is favorable for charging, storing and discharging the magnetic energy in an HTS coil of a SMES system.
