| Abstract: | This paper,by means of maths models and simulation,starts with an analysis of the effect of dead time on inverters in their output voltage and additional harmonic.It then discusses the vector deviation of magnetic chain and extra consumption in the motor load.Several methods for dead time compensation analysis are proposed in the hope of increasing the value of SPWM technology in actual frequency conversion systems. |
