Time delay must be inserted in the switching signals to prevent the simultaneous conduction of two switching devices in the same leg of the inverter, however, this results in a decrease of the fundamental component and an increase of the odd-order except the triple-n harmonics of the output voltage of the inverter. The distortion of output voltage further distorts the output current in turn. This paper analyses the dead-time effect in detail under Space Vector Pulse Width Modulation (SVPWM… CONTINUE READING
