In this paper a new superconductive magnetic energy storage (SMES) system utilizes a high-frequency series resonant dc link power converter of high efficiency as the conditioning converter is presented. This system generates a high-frequency (20 kHz or more) resonant current in a series link and switching is done at zero current instants, reducing switching losses to a minimal value. Through the utilization of an adequate control strategy, the input power factor can be fully adjusted during the charging, storing, and discharging modes of the SMES, improving the overall system efficiency. Different semiconductor devices are employed as the switching elements of the resonant converter and switching losses are established for each case. Experimental results from a monophase and three-phase system verified the results obtained from digital simulation.
