Suppose during the positive half cycle of a.c. input, the end A is positive and the end B is negative with respect to the centre tap T. Then the diode D<sub>1<\/sub> gets forward biased and conducts current along the path AD<sub>1<\/sub> XYTA, as indicated by the solid arrows. The diode D<sub>2<\/sub> is reverse biased and does not conduct. During the negative half cycle, the end A becomes negative and the end B becomes positive with respect to the centre tap T. The diode D<sub>1<\/sub> gets reverse biased and does not conduct. The diode D<sub>2 <\/sub>conducts current along the path BD<sub>2<\/sub> XYTB, as indicated by broken arrows. As during both half cycles of input a.c. the current through load R<sub>L<\/sub> flows in the same direction (X \u00e0 Y), so we get a pulsating d.c. voltage across R<sub>L<\/sub>, as shown in below Fig. Since output voltage across the load resistance R<sub>L<\/sub> is obtained for both half cycles of input a.c., this process is called full wave rectification and the arrangement used is called full-wave rectifier.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"395\" height=\"467\" src=\"https:\/\/successrouter.com\/articles\/wp-content\/uploads\/2022\/11\/image-14.png\" alt=\"\" class=\"wp-image-348\" srcset=\"https:\/\/successrouter.com\/articles\/wp-content\/uploads\/2022\/11\/image-14.png 395w, https:\/\/successrouter.com\/articles\/wp-content\/uploads\/2022\/11\/image-14-254x300.png 254w\" sizes=\"(max-width: 395px) 100vw, 395px\" \/><figcaption>Fig. Waveforms of input a.c. and output voltage obtained from a full wave rectifier.<\/figcaption><\/figure><\/div>\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Junction diode as a full wave rectifier: A full wave rectifier consists of a transformer, two junction diodes D1 and D2 and a load resistance RL.
