Abstract :
This paper overviews the most significant control methods of the induction motor (scalar control, field oriented control (FOC), direct self control (DSC), direct torque control (DTC)) and proposes a brief analysis of their major advantages and drawbacks. In a second stage, the interest of multi-level static conversion for medium voltage applications (up to 6.6 kV rated motors) is pointed out and some topologies are presented and discussed (cascaded association of 2-level converters, neutral point clamped (NPC), multi-cell). Some industrial realizations of medium voltage drives, using the above mentioned control methods and converter topologies, are also referred to for illustration
