CORRECTION OF FLUX ERROR IN LOW SPEED RANGE OF DTC DRIVES OF INDUCTION MACHINES

Mohsen Dashtbani; Majid Hasanzadeh; Reza Roshanfekr

Volume 2, Issue 2 , April 2022, , Pages 26-33

https://doi.org/10.30503/eecs.2023.396796.1038

Abstract
  The conventional direct torque control (DTC) method suffers a flux drop at low speeds, which is due to the long selection of zero (neutral) voltage vectors in these speed areas. Past studies with the continuous switch of direct and reverse active vectors to achieve proper flux adjustment, this procedure ...  Read More

Two structures for controlling multiphase BLDC motors in fault mode and high reliability

mohammadmahdi kazemi; alireza rezazade

Volume 2, Issue 1 , January 2022, , Pages 38-43

https://doi.org/10.30503/eecs.2023.305974.1027

Abstract
  In this paper, two different structures of a multiphase inverter for controlling a Brushless DC (BLDC) motor are presented and compared parameters These two structures are in fault mode. In the first structure, each phase of the BLDC motor is fed from an individual H-Bridge inverter, which is controlled ...  Read More
