Abstract

The dead time deteriorates the output performance of the PWM inverter so that various compensation schemes have been proposed. If the modulation index is rendered with the low output frequencies, those schemes do not work well because of the zero clamping phenomena. In this paper, we investigate the influence of the dead time minimization algorithm on the low output voltage reference. The validity of the algorithm is examined by comparing the simulation results with those of conventional methods.
