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.


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 does the current equals in a bridge rectifier?

In a bridge rectifier, the current output is the same as the input AC current during the positive half-cycle of the AC waveform. However, during the negative half-cycle, the diodes in the bridge configuration allow current to flow in the same direction, effectively converting AC to DC. The output current can be influenced by the load connected to the rectifier and may vary based on the input voltage and the characteristics of the rectifier 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 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.


If input frequency of a full wave rectifier be n then uotput frequency would be?

The output frequency of a full wave rectifier will be twice the input frequency. This is because full wave rectifiers process both the positive and negative cycles of the input signal, effectively doubling the frequency in the output waveform.

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.


What is the output frequency of a half wave rectifier circuit if its input voltage has a frequency of 50 Hz?

The half-wave rectifier is conducting during only half of each cycle, so the fundamental output frequency is 50 Hz, and there are loads of harmonics of 50 Hz. also present in the output.
