Which rectifier requires four diodes?
full-wave bridge circuit
voltage quadrupler
half-wave voltage doubler
full-wave voltage doubler
To get a peak loa d voltage of 40V out of a bridge rectifier. What is the approximate rms value of secondary voltage?
0 V
14.4 V
28.3 V
56.6 V
The use of a capacitor filter in a rectifier circuit gives satisfactory performance only when the load
current is high
current is low
voltage is high
voltage is low
The ripple factor of a bridge rectifier is
0.482
0.812
1.11
1.21
The maximum efficiency of full wave rectification is
40.60%
100%
81.20%
85.60%
The main reason why a bleeder resistor is used in a dc power supply is that it
keeps the supply ON
improves voltage regulation
improves filtering action
both (b) and (c)
The bridge rectifier is preferred to an ordinary two diode full wave rectifier because
it needs much smaller transformer for the same output
no center tap required
less PIV rating per diode
all the above
The basic reason why a full wave rectifier has a twice the efficiency of a half wave rectifier is that
it makes use of transformer
its ripple factor is much less
it utilizes both half-cycle of the input
its output frequency is double the line frequency
The basic purpose of filter is to
minimize variations in ac input signal
suppress harmonics in rectified output
remove ripples from the rectified output
stabilize dc output voltage
In a rectifier, larger the value of shunt capacitor filter
larger the peak-to-peak value of ripple voltage
larger the peak current in the rectifying diode
longer the time that current pulse flows through the diode
smaller the dc voltage across the load
In a LC filter, the ripple factor
Increases with the load current
increases with the load resistance
remains constant with the load current
has the lowest value
