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.
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 %.
