Abstract :
In this paper, a high power NPC three-level inverter equipped with integrated gate-commutated thyristor (IGCT) is introduced and a hybrid space voltage pulse width modulation (SVPWM) method for three-level inverter is also proposed. By hybrid PWM the performance of the system is improved distinctness. The validity of the proposed PWM method is verified by experiment with a NPC three-level inverter equipped with 4.5 kV/4 kA IGCTs.
