| Abstract | This paper presents a simplified space vector pulse width modulation (SVPWM) based diode clamped threelevel inverter fed direct torque controlled (DTC) induction motor drive. The space vector diagram of three-level inverter is simplified into two-level inverter. So the selection of switching sequences is done as conventional two-level SVPWM method. Thus, the proposed algorithm reduces the complexity involved in the PWM algorithm. To validate the proposed PWM lgorithm, several simulation studies have been carried and resultsare presented. From the results, it can be observed that the proposed algorithm reduces the total harmonic distortion (THD) of the line current and line voltages when compared with the 2-level inverter fed induction motor drive. |
