what is the difference of half wave and full wave rectifier |
Rectifier are used to convert AC signal into fluctuating D.C Half wave rectifier These type of rectifier converts only one half of AC into DC signal, either positive or negative cycle. As it rectifies AC partially its efficiency is also less. Maximum efficiency is 40.6%. Half wave rectifier needs only single diode for rectification. Full wave rectifier It converts entire AC into fluctuating DC that is it covert both half cycle to DC. Therefore its efficiency is almost double of half wave rectifier. Efficiency is 81.2 %. It consist of more than one diode. Here positive half cycle is converted by one diode and negative half cycle is converted by other diode. Commonly used full wave rectifier are Centre tapped full wave rectifier and bridge rectifier. |
