Abstract :
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 (N2TV and N2FV) selection laws are suggested to avoid such narrow pulse problems. The experimental verifications for the suggested algorithms are also presented
