Difference Between Half Wave and Full Wave Rectifier



Characteristics
Half Wave Rectifier
Full Wave Rectifier
Definition
The Rectifier that converts only one half Cycle of the input AC supply to DC is called Half Wave Rectifier.
The Rectifier that converts both Halves of the AC input supply Cycle into DC is Called Full Wave Rectifier.
