Abstract :
A novel pulse-width-modulation (PWM) method for a three-level inverter based on space voltage vectors is presented. This PWM method can minimize the harmonic components of the output voltage under the minimum pulse-width limitation gate turn-off thyristors (GTOs) and can also suppress the fluctuation of the neural point DC voltage. Experimental results demonstrate that the proposed PWM method is suitable for a large-capacity three-level GTO inverter applied to motor drives for steel rolling mills, railcars, etc
