Abstract
The analysis of the effect of dead time in a PWM inverter is important to realize its impact on the low frequency harmonics in the inverter and for appropriate dead time compensator design. This paper analyzes the dead-time effect in space-vector PWM (SVM) inverters considering various SVM schemes that include some non-conventional SVMs and even hybrid SVMs. Also, the effect of the current zero-crossing zone in applications with large current ripple is considered in the analysis and it has been found that this inclusion is important. Experimental results are presented that agree with the analysis.
