4、 scheme eliminates requirements of terminal voltage sensing for entire speed operation up to six-step mode. appropriate device on-state drops are compensated to achieve a steady-state operation up to less than 1 Hz Experimental results show that the proposed sensorless drive, with good dynamic performance and smooth operation extending up to six-step mode, can be considered as a replacement to the conventional general-purpose V/f control drive.,Thanks,
