Summary This document represents a work of end of study for the obtaining of diploma of master in électrotechnique under the theme: 'simulation of a speed controlled for a three-phase asynchronous motor' that we studied its various parts. From a three-phase source to a diode bridge rectifier, the output voltage of the rectifier passes through a filter stage and then into a PWM-controlled inverter (Pulse Width Modulation) to provide a voltage input to the motor input. Has variable frequency, which allows varying the speed-
