| Summary: | © 2017 IEEE. This paper presents a control scheme of a threephase three-switch unidirectional delta-Type rectifier, using a modification of discontinuous two-level space vector modulation (2L-SVM) strategy based on Vienna rectifier. The proposed arrange method was created, in order to procreate the discontinuous gate-drive signals for each power switch on the basis of five-segment switching sequence. For this proposal, the switching status of proposed rectifier within the possible operating region is examined carefully, using the diagnosis of operation stages. The duty cycle equations in every current sector are presented by utilizing the determination of the switching time method. Furthermore, the magnitude of output voltage that can be procreated by proposed rectifier is indicated. The feasibility and the effectiveness of the control scheme have been confirmed though the calculation and the computer simulation results. |
