  • A detailed mechanism of generation of narrow gating pulses in conventional nearest three-level vector (NTV) space vector PWM invertors is described and new nonnearest three and four vector (N/sup 2/TV and N/sup 2/FV) selection laws are suggested to avoid such narrow pulse problems. The experimental verifications for the suggested algorithms are also presented.<<ETX>>
