What turns alternating current into pulsating direct current?

Explanation:
Rectifier circuits convert alternating current into pulsating direct current. They use diodes to allow current to pass in only one direction, so each half-cycle of AC is turned into a unidirectional pulse. The result is direct current with ripples, i.e., pulsating DC. A transformer changes AC voltage but doesn’t convert to DC. An inverter turns DC into AC. A filter smooths the pulsating DC but doesn’t perform the conversion itself.
