3-LEVEL SPACE VECTOR PWM IN LOW-INDEX MODULATION REGION AVOIDING NARROW PULSE PROBLEM

open access: yes, 1994
In using GTO, a few hundreds micro seconds longer than specified pulse width must be guaranteed for safety for each device to commutate with its inherent gate current Sequences.

Reduction of Torque Ripple in Induction Motor Drives Using an AdvancedHybrid PWM Technique

open access: yes, 2010
A voltage source inverter-fed induction motor produces a pulsating torque due to application of nonsinusoidal voltages. Torque pulsation is strongly influenced by the pulsewidth modulation (PWM) method employed.

Current-error space-vector-based hysteresis PWM controller for three-level voltage source inverter fed drives

open access: yes, 2005
A current-error space-vector-based PWM hysteresis controller is proposed for three-level voltage source inverter fed induction motor drive applications. A hexagonal boundary for the current-error space vector is formed by sensing the current-error space ...
