Solution
A full-wave bridge rectifier has several advantages over a half-wave rectifier:
-
PIV rating is halved: In a full-wave rectifier, the peak inverse voltage (PIV) is half of that in a half-wave rectifier. This means that the diodes in a full-wave rectifier only need to withstand half the voltage, making them less likely to break down.
-
Filter capacitor can discharge more quickly: In a full-wave rectifier, the output frequency is double that of the input frequency. This means that the filter capacitor discharges more quickly, resulting in a smoother output voltage.
-
Peak diode current is halved: In a full-wave rectifier, the current is shared between four diodes instead of two. This means that the peak current through each diode is halved, reducing the risk of diode failure.
-
Suitable for high voltage applications: Because the PIV is halved and the peak diode current is also halved, full-wave rectifiers are more suitable for high voltage applications.
-
Surge current reduces with filter capacitance: The surge current in a full-wave rectifier is less than in a half-wave rectifier. This is because the filter capacitor in a full-wave rectifier discharges more quickly, reducing the surge current.
-
Only requires two diodes: This is not correct. A full-wave bridge rectifier actually requires four diodes, not two. This is a disadvantage compared to a half-wave rectifier, which only requires one diode.
-
Cheaper to manufacture: This is not necessarily true. While a full-wave rectifier requires fewer components than a half-wave rectifier, the components it does require (four diodes) can be more expensive.
-
Filter capacitor required is halved: This is not correct. The filter capacitor required for a full-wave rectifier is actually the same as for a half-wave rectifier. However, because the full-wave rectifier discharges the capacitor more quickly, it can produce a smoother output voltage with the same size capacitor.
