For any current to flow, two of the diodes must be turned on at any given time, depending
on the polarity of the AC sine wave at the transformer secondary winding. Because two
diodes conduct at any given time, there are two diode voltage drops for the complete cur-
rent to flow through. This means that the power dissipated by the full-wave bridge is 1.4 V
× current, which is twice that of the full-wave center-tapped rectifier.
Since current is delivered to the load during both halves of the cycle and since there is no
need for identical secondary windings on both sides of a center tap, the full-wave bridge
requires the least expensive transformer. However, the full-wave bridge has twice the
power dissipation of the full-wave center-tapped rectifier. The full-wave bridge cannot be
used with triacs and other circuits based on zero-crossover detection because there is no
common ground.
