| Abstract: | Based on the problem that exists in the motor＇s regeneration energy feedback applied technology, this paper used the duaI-PWM VVVF technology. A current control PWM- rectifier based on the fixed-switching frequency SVPWM was designed, and good control results are obtained in the application on the machine tool＇s electric drive control system. |
