一种用于制糖工业甘蔗破碎机的四电平逆变器供电开口绕组感应电机驱动系统

This article presents a four-level inverter fed open-end winding induction motor drive, consisting of coupled motors, for the sugarcane shredding machine of the sugar industry. In the existing two-level inverter-fed variable frequency drive, there are drawbacks such as high harmonic distortions in the input current and inverter output voltage, high common mode voltage, and higher dV/dt stress on i...
