Abstract

Based on the conventional traction drive three-level inverter SVPWM complexity, a simplified SVPWM method is proposed based on the intrinsic relationship between two-level inverter and t-type three-level inverter. To begin, it analyzes the working of t-type topology. In addition, it simplifies the t-type three-level inverter control method based on sins theorem and mapping relationship between two-level inverter and traditional SVPWM method. Meanwhile, Feedback neutral-point potential voltage control is discussed. It is proved that the simplified method can be applied to the t-type three-level inverter based on traction drive by the simulation analysis.
