What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.
What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
Why does the output frequency of a full wave rectifier double that of input frequency?
One cycle of the AC input consists of a positive half-cycle followed be a negative half cycle. The FW rectifier basically reverses the polarity of one of the half-cycles, so there are now two positive pulses per single input cycle, effectively doubling the frequency. Of course the rectifier may be wired for the opposite polarity, with two negative pulses per input cycle, but the same principle applies.
. Which type of full-wave rectifier has the greater output voltage for the same input voltage and transformers turn ratio?
well when you see on basis of output voltage the centre tapped transformers is .
What is the peak value of the input to a half wave rectifier if the half wave rectifier is 10V?
In this case, the peak voltage, which is half the peak to peak voltage, is 100 volts. Additionally, the half-wave rectifier will only provide an output for half the input cycle. In the case of a full wave rectifier, the RMS output voltage would be about 0.707 times the value of the peak voltage (100 volts), which would be about 70.7 volts. But with the output operating only half the time (because of the half wave rectification), the average output voltage will be half the 70.7 volts, or about 35.35 volts RMS.
What is output frequency of bridge rectifier?
twice the input frequency
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
What does the out put wave form looks in a rectifier?
A rectifier allows current to flow only in one direction. In a half-wave rectifier circuit, an input wave which oscillates between positive and negative, will 'pass through' the positive portion of the wave, and when the input is negative will output zero. A full-wave rectifier circuit, is commonly configured with 4 rectifier diodes, which allow a positive wave to output when the input wave is negative.
How do rectifier circuits stabilize the output voltage when the input voltage is subject to fluctuations?
Rectifiers don't "stabilize the output voltage" of rectifier circuits when input voltage fluctuates. The rectifiers just rectify the input, and the output will fluctuate as the input does. Another form of "conditioning" of the rectified output is needed to address the issue of fluctuations. And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Through regulation, the output will be resistant to changes in voltage when changes in the input voltage occur.
What is the number of dc pulses in the output of a full-wave rectifier whose input frequency is 50 Hz?
Output of the 50 Hz full-wave rectifier consists of 100 Hz positive pulses.
What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.

How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Why does the output frequency of a full wave rectifier double that of input frequency?
One cycle of the AC input consists of a positive half-cycle followed be a negative half cycle. The FW rectifier basically reverses the polarity of one of the half-cycles, so there are now two positive pulses per single input cycle, effectively doubling the frequency. Of course the rectifier may be wired for the opposite polarity, with two negative pulses per input cycle, but the same principle applies.
What is a fully controlled rectifier?
A controlled wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Controlled wave rectification converts both polarities of the input waveform to DC (direct current), and is more resourceful.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
. Which type of full-wave rectifier has the greater output voltage for the same input voltage and transformers turn ratio?
well when you see on basis of output voltage the centre tapped transformers is .
