TY - JOUR ID - TI - HYBRID MODULAR MULTILEVEL CONVERTER FOR VECTOR-CONTROLLED INDUCTION MOTOR DRIVE AU - Turki K. Hassan AU - Ahmed K. Hannan PY - VL - IS - Conference proceedings 2020 SP - 143 EP - 154 JO - Journal of Engineering and Sustainable Development (JEASD) مجلة الهندسة والتنمية المستدامة SN - 25200917 25200925 AB - Application of traditional modular multilevel converter (MMC) for medium voltage induction motor drive is difficult especially at low frequencies of drive due to large peak to peak ripple of sub-module (SM) capacitor voltage. In this paper, a hybrid MMC is used to obtain lower peak-to-peak capacitor voltage ripple, specifically at low motor speed. Field oriented control strategy for induction motor created on closed-loop speed controller is suggested to have an accurate and wide speed range of speed. The Matlab/Simulink is used for simulation, the simulation results of induction motor drive with hybrid and traditional MMC are obtained and compared from the point of view of capacitor voltage ripple. The results show the reduction voltage ripple of SM capacitor as the hybrid MMC is operated.
