Abstract: A method and apparatus for adaptive rectification for preventing current inversion in motor windings are provided. In the method and apparatus, first and second half bridges of a plurality of half bridges are operated to synchronously rectify and permit passage of current, through the windings of the motor, in a first direction. A change of direction of the current from the first direction to a second direction opposite the first direction is detected. In response to detecting that the current changed direction to the second direction, the first and second half bridges of the plurality of half bridges are operated to quasi-synchronously rectify and block passage of the current through the windings in the second direction.
