Abstract :
On the basis of soft-switched inverter, an improved stator direct self control (DSC) using band width prediction (BWP) of an induction motor is proposed. The response of DSC is slower during start-up and during change in command torque. The BWP is used for implementation to improve its slow response. The zero vector is not adopted in the BWP control, this not only improve the response of DSC, but also reduces the effect of the stator resistor, especially at low speed. The simulation and result is proposed to verify the BWP
