Dead-Time Inverter Voltage Drop in Low-End Sensorless FOC Motor Drives.

The purpose of this study was to investigate the impact of voltage drop of a three-phase voltage source inverter on driving brushless motors. This study also proposes an enhanced field-oriented control scheme that accounts for inverter voltage drop, enabling efficient driving at very low motor speeds. Experimental results are provided to verify the theoretical study and the proposed control scheme. [ABSTRACT FROM AUTHOR]
