A multimodule hybrid converter for high-temperature superconducting magnetic energy storage systems (HT-SMES)

A multimodule hybrid converter mainly designed for use in high-temperature superconducting magnetic energy storage systems (HT-SMES) is investigated in this paper. The converter consists of a four-module current-source converter and one module of voltage-source converter to reach the high power rating and low harmonics requirement of the HT-SMES. Circuit topology, control method, and simulation results are given.
