The above statement is True.
The direction of the current changes itself after every half rotation, and the split-ring commutator reverses this current direction after every alternate half rotation. It converts the current direction in every half-cycle to positive. Thereby, it converts AC to DC. This slip-ring commutator essentially maintains a connection between the rotor and the stator.
