4、es 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 HzExperimental 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,
