Which rectifier have highest ripple frequency?
The three phase bridge rectifier has the highest ripple frequency. In a 60 Hz system, the ripple frequency would be 360 Hz. If it were a one phase bridge rectifier, the ripple frequency would be 120 Hz.
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
How could you measure ripple frequency to determine if a diode were open in a bridge rectifier circuit?
Measuring ripple frequency would determine if a diode were open in a bridge rectifier circuit because the ripple frequency is normally twice the input frequency in a functioning full wave bridge rectifier. If one diode were open, the ripple frequency would only be the input frequency. Note: This is true for single phase or bi-phase operation. Three phase operation is more complex, but still doable - You would expect three times input frequency in normal state, and two times (asymmetric) with one open diode.
What is the main difference between a bridge rectifier and a full wave rectifier?
Both the bridge rectifier and the full-wave rectifier achieve the same thing. They rectify the AC input on both opposing phases so as to minimize ripple time and voltage. The difference is that a bridge rectifier consists of four diodes arranged in a bridge, so the input needs to only be single phase AC, while a full wave rectifier consists of two diodes, but needs a split phase AC source, such as provided by a center tapped transformer winding. Also, the bridge rectifier presents two junction drops in the output, because there are always two diodes in series, while the full-wave rectifier presents only one junction drop in the output, because there is only one. It is a trade-off.
What is the lowest ripple frequency of half wave rectifier?
The ripple frequency of a half-wave rectifier is the same as the input frequency.
Which rectifier have highest ripple frequency?
The three phase bridge rectifier has the highest ripple frequency. In a 60 Hz system, the ripple frequency would be 360 Hz. If it were a one phase bridge rectifier, the ripple frequency would be 120 Hz.
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
What happens to the output when one of the diode becomes open in full wave bridge rectifier?
The output degrades to a half-wave rectifier.
Which harmonics is present in full bridge rectifire?
Since the output of the rectifier is a close approximation of a sawtooth waveform, then all harmonics starting at the second harmonic are present in the full wave bridge rectifier output.
Why dc output voltage of a bridge rectifier varies with the load current?
aA A: the output of a Bridger's rectifier will always follows proportionally to the load since it does not regulate the output it merely transform AC TO DC '
Why bridge rectifier is prefer over center type rectifier for low voltage applications?
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
Why the output wave shape of the rectifier is disorted at high frequency supply?
A: A rectifier is simply a diode or is it? At hi frequency the storage time or the disconnect time becomes significant that is why it looks distorted to the scope
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.
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 basic difference between a full wave bridge rectifier and a full wave center tapped rectifier?
A full-wave bridge rectifier with 4 diodes gives a dc output voltage equal to the average voltage of the whole transformer secondary. A FW rectifier with 2 diodes and a centre-tapped secondary gives an output voltage equal to the average voltage of half the secondary. If you have a 12-0-12 transformer, the bridge gives a 24 v output, while the 2-diode FW rectifier gives 12 v (approximately).
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 is the advantage of using the bridge rectifier over the conventional full wave circuit?
Output voltage is higher!!!
