摘要：

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. This paper describes the mechanism of generating undesirable narrow pulses in conventional three-level space vector PWM and suggests two new algorithms of space vector PWM using Non-Nearest three and four vectors in a control period to avoid such a narrow pulse problem. Experimental verifications for the suggested algorithms are also presented.
