A Novel Suppression Method for Low-Order Harmonics Causing Resonance of Induction Motor
In the motor drive system of electric vehicles, there are some nonlinear factors, such as the deadtime and the conduction voltage drop of switching devices, which will generate low-order harmonics of the stator current and the torque ripple.The frequency of the harmonic may coincide with the natural frequency of the motor, so resonance may occur on
