Semester IV – B.E.
In a Full Wave Rectifier circuit 4 diodes are used, 2 for each
half of the cycle. A multiple winding transformer is used
whose secondary winding is split equally into two halves with
a common centre tapped connection, (C). This configuration
results in each pair of diode conducting in turn when its anode
terminal is positive with respect to the transformer centre
point C producing an output during both half-cycles, twice
that for the half wave rectifier so it is 100% efficient as shown
below.
The power diode in a half wave rectifier circuit passes just
one half of each complete sine wave of the AC supply in
order to convert it into a DC supply. Then this type of circuit
is called a “half-wave” rectifier because it passes only half of
the incoming AC power supply as shown below.
Another type of circuit that produces the same output
waveform as the full wave rectifier circuit above, is that of the
Bridge Wave Rectifier. This type of single phase rectifier uses
four individual rectifying diodes connected in a closed loop
“bridge” configuration to produce the desired output.
The main advantage of this bridge circuit is that it does not
require a special centre tapped transformer, thereby reducing
its size and cost. The single secondary winding is connected
to one side of the diode bridge network and the load to the
other side as shown below.
