GDB Question
The full-wave rectifier and Bridge rectifier both
are used for full rectification, then what feature of each advantage over to
the other. What Peak Inverse Voltage (PIV) value determines in each rectifier.
Solution
Advantages of bridge rectifier over Full Wave
Rectifier
·
The main advantage of the bridge rectifier
over full-wave rectifier is that it produces twice output voltage comparatively as produced by full-wave
center-tapped transformer using the same secondary voltage.
· The advantage of bridge rectifier over a full-wave rectifier is that if free from the burden of centrally tapped
transformers.
· The Bridge Rectifier enjoys more
transformer utilization factor (TUF) that gives it an extra edge over the full-wave
rectifier.
Full wave rectifier advantages over bridge rectifier
· The full-wave rectifier has 2 numbers of
diodes while bridge rectifier has 4 numbers of diodes
Peak Inverse voltage (PIV)|Peak Reverse Voltage (PRV)
PIV or PRV refers to the maximum value of reverse
voltage when the input cycle is at its peak provided that diode is reversed-biased.
Therefore, in the case of the full-wave rectifier, its value is 2Vmax but in the bridge
rectifier, its value is half that is Vmax.
