Definitions:

Rectifiers

Electrical devices that convert alternating current (AC) to direct current (DC), allowing the flow of charge in one direction only, and are widely used in power supply units and electronics.

Converters

Devices that transform energy from one form to another, such as AC to DC in electrical systems, or physical units in digital systems.

Amperes

The unit of electric current, representing the flow of one coulomb of charge per second.

Watts

The SI unit of power, representing one joule per second, used to quantify the rate of energy transfer.
