Full-Wave Rectifiers                There are two types of full-wave rectifier circuits.one is uses two diodes with a center tapped transformer and the transformer have equal turns Ns1 and Ns2 of the secondary windings which is shown in the fig. below The second type of FW-rectifier is having bridge-rectifier circuit and uses four diodes and it does not require a center-tapped transformer it only have simple transformer. fig. Comparison of HW Rectifiers and FW  Rectifiers                  The FW-rectifier circuits are better if we compare with HW rectifier circuits in all most all respects.FW-rectifiers have double the value of dc voltage delivered to load their efficiency is also double and their ripple factor is low.Due to these reasons FW-rectifiers are preferred over HW-rectifiers.
