What's Difference Between Power Supply And Rectifier?

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.

The rectifier circuit takes alternating current (AC) and converts it into a positive direct current (DC) output. Many power supplies, such as standard electrical output, produce AC voltage. Many handheld tools and other devices use DC. The rectifier is to provide desired DC power for the application.

A Power Supply provides power at the desired voltage using a transformer and may also as a rectifier to convert it to DC.Power supply includes AC power supply and DC power supply.
