摘要：

In this paper it is proposed a new three-phase multilevel power conversion structure. This structure uses a three single-phase voltage source inverters and Scott transformer. The structure composed by the three single-phase voltage source inverters has two single-phase outputs. These outputs will connect to the Scott transformer. This transformer allows deriving two-phase voltage to a three-phase source. The proposed multilevel power conversion structure allows obtaining a five-level three-phase inverter. To control the proposed power converter it is used a sliding mode controller with a vectorial modulator. Several test results of the proposed converter structure with their control system are presented. From the obtained results it is possible to confirm the voltage multilevel waveforms and the effectiveness of the proposed control system technique.
