Abstract :
Relative high-power applications of inverters have been undergoing in recent years. This paper describes a composite PWM method of parallel combination with two three-phase GTO bridge inverters suitable for high-power applications. The effective switching frequency of the PWM VSI is increased to twice the real switching frequency of GTO switches
