If the input frequency to a full wave rectifier is 400Hz what is the ripple frequency?
twice the frequency that is rectified.
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 calculate the capacitance value of filter capacitor for full-wave bridge 12VDC power supply?
THe Filter capacitor value depnds on the maximum current I of the Power supply , Switching frequency and the permissible ripple C= (I * (1/2f ))/ ( V * %Ripple) - for a full wave rectifier C= (I * (1/f ))/ ( V * %Ripple) - for a Half wave rectifier Where C= Capcitance in Farads I = Current in Amps f = Switching Frequency V = Nominal voltage in this case 12 V Reji J Thoppil
What is ripple frequency of 50 hz ac full supply?
you can't have half wave rectified polyphase AC power, unless you are using only one of the phases. however with only one diode from each phase of three 50 Hz phases the ripple frequency is 150 Hz, with two making a full three phase bridge the ripple frequency is 300 Hz. perhaps that was what you meant.
What is advantage of precision full wave rectifier over precision half wave rectifier?
Either less ripple voltage with the same filter capacitance, or similar ripple voltage with smaller filter capacitances (and thus physically smaller filter capacitors).
Differentiate half wave doubler to full wave doubler which is more efficient?
depends on how you define efficiency full wave uses both sides of the ac cycle half wave one half wave is less components same output perhaps bigger capacitors full wave is more components balanced loading less ripple or double the frequency of the ac with less ripple forward voltage drop through diodes Si .7V so with full wave bridge 1.5 v at output current serves only to heat the diodes quite a consideration for those new 1V cpus
How does the full wave doubler works?
full wave doubler works like a doubler but difference is in doubler you will get only double of your input. in full wave doubler you will get a doubler of your doubler...
Formula how to calculate voltage ripple peak to peak?
For Half wave rectification: Vr(HW) = I/(C*F) HW= Ripple Voltage I = Direct Current C= Capacitance F= Frequency of the ac line. For full wave rectification: Vr(HW) = I/(2*C*F)
If the input frequency to a full wave rectifier is 400Hz what is the ripple frequency?
twice the frequency that is rectified.
What is ripple frequency of 50 Hz 3 phase full ac supply?
A single phase half wave rectifier outputs ripple the same frequency as the input. A single phase full wave rectifier outputs ripple fundamental twice the input frequency (assuming balanced recitfiers). A three phase full wave rectifier outputs ripple fundamental six times the input frequency. So 50 Hz input would yield 300 Hz ripple. See Sources and Related Links for more information.
What are the advantages of half-wave rectifiers over full-wave rectifiers?
The full-wave rectifier conducts on every half cycle, whereas the half-wave rectifier conducts on every other half cycle.This halves the average current on each diode, halving the power dissipated by the diodes.It doubles the ripple frequency, making filtering easier.Since the ripple frequency is doubled, the peak-to-peak ripple voltage is approximately half, which means that less capacitance is required in the filter capacitor.Since the peak-to-peak ripple voltage is lower, the head-room between filtered and regulated voltage is less, meaning less power is dissipated by the regulator.Full wave rectifiers give a smaller output voltage ripple, resulting in a smoother output waveform. However, depending on the design, the output on a full wave rectifier may be slightly less (like around 0.4V less) than that of a half wave rectifier. This is normally due to the voltage drop increasing due to the presence of additional diodes in the circuit.
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.

Is welding transformer a frequency changing transformer?
Not really. Frequency in is frequency out, unless there is some conversion circuit in between, such as a motor-generator set or some kind of inverter. You may (and should) notice, however, that a typical welding transformer is rectifying three phase AC to DC, using a full wave rectifier. This results in a pulsating DC voltage where the ripple frequency is 360hz.
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.
