چکیده
Balancing control of neutral-point voltage (NPV) and reducing common-mode (CMV) are crucial for a three-level neutral-point-clamped (NPC) inverter. NPV oscillation can be inhibited by constructing virtual vectors adding adjustment factors to eliminate stochastic disturbances that cause unbalanced NPV. However, the significantly increase computational complexity introduce dynamic sector split instead traditional static one. Moreover, prompts considerable rise in CMV. Therefore, this paper proposes space vector modulation strategy NPC inverter eliminates reduces The study applies idea carrier-based (CBM), which calculation time caused novel factors. A method determine maximum is designed evaluate regulation ability, analysed. basic VSVM theoretically compared, it proved has better capability than under high ratio power factors, such as motors systems.
