Detailed explanation-1: -A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.
Detailed explanation-2: -The commutator on the DC generator converts the AC into pulsating DC. The commutator assures that the current from the generator always flows in one direction. The brushes ride on the commutator and make good electrical connections between the generator and the load.
Detailed explanation-3: -A rectifier converts alternating current to direct current and this process of converting AC to DC is known as rectification.
Detailed explanation-4: -As its name implies, a DC-DC converter converts one DC voltage to another. The operating voltage of different electronic devices such as ICs can vary over a wide range, making it necessary to provide a voltage for each device.
