Title
Space Vector Modulation Strategy Of Three Phase Multilevel Current Source Rectifer
Abstract
Space vector pulse width modulation (SVPWM) technology is widely used in power converters as a modulation strategy that can effectively improve voltage utilization and reduce harmonics. However, as the number of levels increases, the number of space vectors suddenly increases, and the modulation algorithm design and implementation become more and more difficult. As a result, such application is hardly seen in three-phase multilevel current source rectifier (MCSR). This paper proposes a basic theory and control algorithm of SVPWM technology applied in 7-level rectifiers, which adopts a double closed-loop control strategy for inner current loop and outer voltage loop. System modeling and theoretical analysis with detailed vector selection method of the proposed control are provided. Simulation results show that both unit power factor and 7-level waveforms have been achieved, which has validated the proposed control.
