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 process is known as rectification, since it “straightens” the direction of current.
How does a rectifier works?
The rectifier circuit, which is typically made from a set of cleverly interlocked diodes, converts alternating current to direct current. In household current, the voltage swings from positive to negative in cycles that repeat 60 times per second.
What is the use of a diode?
Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators. The fundamental property of a diode is its tendency to conduct electric current in only one direction.
