| Abstract: | In order to srudy three-level inverters using in high voltage,high power motors drive applications,the switch model and topolgical were analyzed in detail,the mathematic model of the asynchronous motor was presented,then a method that SVPWM control convert bridge was proposed.The simulation results indicate that the method can effectively realize three-level SVPWM control and high performance speed-regulation of asynchronous motor. |
