The dead time necessary to prevent the short circuit of the power supply in pulse width modulated (PWM) voltage inverters results in output voltage deviations. In this paper, the novel control method for a single-phase half bridge inverter based on the direction of filter inductor current is presented based on the hysteresis control technique. The switches driving signals of half bridge inverter is...
Various studies have showed that about 70 to 90% of single line to ground faults occurred on High voltage transmission lines have transient nature. This type of faults is cleared by temporary outage (by the single phase auto-reclosure). The interval between opening and reclosing of the faulted phase circuit breakers is named "Dead Time" that is varying about several hundred milliseconds...
The impact of common-mode voltage generated by PWM AC drives on motor bearings is well known. Several algorithms for common-mode voltage reduction have been proposed in the literature. While a few algorithms assume ideal switching and fall apart when non-idealities like inverter dead time are considered, some others are effective only in a limited operating range of the drive. In this paper, a previously...
