用于牵引应用的同步正弦PWM感应电机转子磁场定向控制

This paper proposes a vector-controlled squirrel cage induction motor drive with synchronized sinusoidal pulse width modulation (PWM) for traction applications. In traction applications, switching loss in insulated-gate bipolar transistors is very important, and hence, a switching frequency of few hundred hertz is used in these devices. A triangular carrier comparison-based synchronized sinusoidal...
