description The technological revolution in transportation whether on land, at sea, or in the air – has reached the stage of electrification. This revolution has indicated a rise in demand in recent years for a power supply system. The typical converters to control four-quadrant operation of a permanent magnet DC motor requires at least two separate circuits including the integration of current wave shaping supply technology to ensure high power factor operation. The use of at least two separate converters circuits contributes to the increase in the number of semiconductor devices, which leads to their bulky size, high power semiconductor losses and low power density. Therefore, this thesis proposes a new model of single-stage direct control of DC machines fed with AC voltage sources using a single-phase matrix converter (SPMC).
