The dead time along with the other inverter non-idealities are known to distort the inverter
output voltage. This affects the performance of all electrical drives at the low and medium
speed range resulting into inacceptable performance. Sensorless drives are the most
affected ones with this phenomenon compared to the other electrical drives. This paper
proposes a quantitative mathematical analysis to the motor's current harmonics induced due
to the dead time and inverter non linearity. The mathematical analysis is validated using …

Sensorless drives are the most affected ones with this phenomenon compared to the other electrical drives. This paper proposes a quantitative mathematical analysis to the motor's current harmonics induced due to the dead time and inverter non linearity.
