What is meant by ripple voltage?
Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform after rectification.
How do you read ripple voltage?
Select the “AC voltage” mode by turning the tester knob. The meter will only measure the AC component of the signal, the ripple voltage, if present. The display shows the measured value of the ripple voltage amplitude. If it shows the value 0.00 mV it means that, most likely, the ripple is absent.
How do you find the ripple factor on a graph?
Ripple factor = √(Vrms/Vdc)2-1=√(Vm/2/Vm/Π)2-1 = 1.21. Effieiency = (Vdc/Vrms)2 = (Vm/Π/ Vm/2)2=0.405X100= 40.5%. Graph : Trace the Input and Output waveform of half wave rectifier without and with filter observed in DSO.
What is ripple voltage equation?
Ripple factor, γ = RMS value of AC component in rectifier output/Average value of rectifier output. γ = I'rms/Idc = V'rms/Vdc. In the above equation, I'rms is the alternating component of load current. V'rms is the alternating component of voltage.
What is ripple in simple words?
a small wave or a slight movement of a surface, esp. the surface of water: The stone hit the water and caused a ring of ripples to spread out. A ripple is also a sound or feeling that is slight but is noticed: A ripple of laughter ran through the crowd.
What is ripple effect in a simple words?
: a spreading, pervasive, and usually unintentional effect or influence. the automotive industry has a ripple effect on many other industries.
Is Lower ripple voltage better?
The lower the ripple factor, the better the filter. The ripple factor can be lowered by increasing the value of the filter capacitor or increasing the load resistance.
Is ripple factor should be high or low?
Smaller value of ripple factor is desirable. Ideal value of ripple factor is zero. Zero ripple factor means a perfectly dc quantity. Undesirable effects of the ripple include equipment heating, increased losses, and reduced equipment life among others.
What is a good ripple voltage?
Acceptable ripple voltage is about 100mV peak to peak. Majority of good power supplies have ripple and noise figures of better than 10mV rms, while SMPS figures of 50mV or less are possible, however, higher current supplies are likely to have slightly higher values.
What does ripple factor indicate?
Ripple factor is defined as the ratio of RMS value of the AC component to the output of the DC component in the rectifier. In other terms, Ripple Factor = RMS (root mean square) value of AC/ RMS value of DC. The ripple factor plays a major role in describing the efficiency of any rectifier.
What is a ripple effect example?
The act of tossing a small stone into the water will result in a change that can be felt much farther away than the initial entry point—proof that small actions can lead to much bigger changes, even if you can't see how far they can reach.
Does ripple mean wave?
A ripple is a small wave on the surface of something, such as a ripple that forms a ring around the spot where you threw a pebble into the pond. Ripple can also be a verb. For example, you might see raindrops ripple on top of a puddle.
What do the ripple represent?
The ripples that appear in a flat surface of water when you throw a pebble into it are often used as a metaphor for the effects of our actions in life—the ones that extend out beyond where we can observe them.

What ripple means?
rippled; rippling ˈri-p(ə-)liŋ intransitive verb. : to become lightly ruffled or covered with small waves. : to flow in small waves. : to fall in soft undulating folds.
What causes high ripple current?
Ripple can be caused by unwanted AC currents coming from the load side, and in this situation more ripple means more heat that must be dissipated in the capacitor. At a certain point this will cause a thermal runoff effect that will eventually cause the capacitor to fail, opening up the circuit.
Is high ripple current better?
The ripple current is the amount of current passing through the cap. Higher current = more power dissipated in the cap which makes it hotter, hotter cap = shorter life. Caps rated at higher ripple current should last longer, but you will need to take several variables into consideration when comparing.
What is a good voltage ripple?
Acceptable ripple voltage is about 100mV peak to peak. Majority of good power supplies have ripple and noise figures of better than 10mV rms, while SMPS figures of 50mV or less are possible, however, higher current supplies are likely to have slightly higher values.
Should ripple factor be high or low?
Smaller value of ripple factor is desirable. Ideal value of ripple factor is zero. Zero ripple factor means a perfectly dc quantity. Undesirable effects of the ripple include equipment heating, increased losses, and reduced equipment life among others.
What does higher ripple factor mean?
The magnitude of the AC component in the output is indicated by the ripple factor. A higher ripple factor indicates that the rectifier's output has a larger AC component.
What ripple effects means?
/ˈrɪp. əl ɪˌfekt/ a situation in which one event produces effects which spread and produce further effects: The bank crash has had a ripple effect on the whole community. Outcomes and consequences.
How do you explain ripple?
Ripple is a blockchain-based digital payment network and protocol with its own cryptocurrency, XRP. Rather than use blockchain mining, Ripple uses a consensus mechanism, via a group of bank-owned servers, to confirm transactions.
What is ripple in simple terms?
: the ruffling of the surface of water. (2) : a small wave. : ripple mark. : a sound like that of rippling water.
What do ripple marks tell us?
Ripple marks are sedimentary structures and indicate agitation by water (current or waves) or wind. Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment.
What is an example of ripple effect?
The act of tossing a small stone into the water will result in a change that can be felt much farther away than the initial entry point—proof that small actions can lead to much bigger changes, even if you can't see how far they can reach.
