The three-level neutral-point-clamped converter has been widely used in medium voltage range for industrial applications, however, the unbalance distribution of power loss of three level NPC converter limit the output power, the three level active neutral point clamped (ANPC) converter provides more flow paths which can improve the balance of power loss distribution. Fault diagnosis in power electronic...
This paper presents a decoupling method for speed-sensorless vector control of induction motor to track the flux command fast and eliminate torque ripples in flux-varying environment, such as field-weakening operation and efficiency optimization. Rotor flux-oriented control can decouple the speed and flux control. However, the decoupling is on the condition of a constant rotor flux. When motor drives...
