Abstract :
This paper presents the modeling, detailed simulation, and test of an efficient medium-voltage adjustable-speed drive. The system consists of a three-level neutral-point-clamped inverter supplied by a 12-pulse rectifier. To achieve a motor-friendly supply, an LC filter is inserted between inverter output terminals and induction motor terminals. A direct torque control tunes the inverter. The full power circuits as well as the digital control scheme have been implemented and simulated. Simulation results have been compared successfully with measurements, in steady state and transients
