【Abstract】 Multilevel converter technology has been mainly used for voltage-source inverters (VSI’s) by now. But with the development of the superconducting magnetic energy storage (SMES) technology, superconducting inductors can be used as higher efficiency energy storage elements, the application of multilevel current source inverters (CSI’ s) in power systems will be more and more popular. A three-phase 6-level inverter using new topology are discussed in detail. The waveforms of output current and current-sharing inductors current of the two inverters under capacitive load and inductive load are provided. The proposition in this paper is verified by results of simulation and experiment.更多还原
