A Multi-Objective Improved Space Vector Modulation Method for Three-Level Inverter

Résumé fourni par la source

This paper investigates the T-type three-level topology. Based on quantitative analysis of voltage generation mechanism, the common mode (CM) reduction space vector modulation (CMRSVM) of T-type three-level inverter was studied. Based on virtual vector construction and regulation, an improved virtual space vector modulation (IVSVM) method was proposed in this paper, which can achieve the neutral-point (NP) voltage control and CM voltage suppression. In addition, the hybrid space vector modulation (HSVM) strategy combining CMRSVM and IVSVM provides an option for achieving comprehensive optimization of modulation performance. Finally, the experiments verified the correctness and feasibility of the proposed method.
