Ripple voltage is when the DC voltage varies between (for example)12.5 Volts and 13.5 Volts, and does so rapidly.
Technically, an alternator produces "alternating current", (hence the name, 'Alternator') and that AC voltage is converted to DC by running the current through a bank of "diodes". Diodes are able to allow current to flow one direction and not the other.
As the voltage runs through the diodes it becomes a form of DC voltage, along with pulsations of up and downs, which is called as ripples. All electronic circuit require a steady DC supply free from these unwanted ripples. Fortunately, a battery when charged by pulsating rectified DC output can smooth out most of those ripples for us. If battery backup is not available in supply then filters ( reactive circuit elements, inductor in series and capacitor parallel to load) circuits can smooth out these ripples and improve quality of rectified output.
BTW, it's called ripple voltage because when you look at the voltage on an oscilloscope it looks like ripples as the voltage varies.

HOW TO MEASURE RIPPLE AC VOLTAGE?
To measure ripple AC voltage, use an oscilloscope or a true RMS multimeter. Connect the oscilloscope probes across the output where the ripple voltage is present, ensuring proper grounding. Set the oscilloscope to an appropriate time base to visualize the waveform, and measure the peak-to-peak voltage to determine the ripple magnitude. For a multimeter, select the AC voltage setting and connect the leads across the same output to get a reading of the ripple voltage.
What type of voltage called ripple voltage?
Ripple voltage is a voltage with an impure wave that isn't stable at all. Usually when you overload an AC to DC converter, it tends to do that.
What is ripple voltage in 12 volt power supply?
A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
Where do you set meter when checking for ripple?
When checking for ripple on a power supply, you should set the meter to the AC voltage setting. Connect the meter probes across the output terminals of the power supply while it is under load, if possible. This allows you to measure any AC voltage fluctuations (ripple) superimposed on the DC output. Ensure that the range is appropriate for the expected ripple voltage level.
Methods of calculating Ripple voltage in supply without using oscilloscope?
Measure AC voltage with multimeter. It is easiest way to check how big ripple is. There is no way to 'calculate' value.
How is ripple measured?
Ripple is measured in terms of the peak-to-peak voltage variation in an AC signal, typically expressed as a percentage of the average voltage level. It is often quantified as a percentage of the DC voltage or as a specific value in millivolts. Lower ripple values indicate a more stable voltage supply.
How do you measure amplitude of a ripple?
Most true RMS voltmeters can measure the value of a ripple voltage on top of a DC supply, when you place it in AC mode. You can also place a small capacitor in series with a DC voltmeter and that would measure the ripple. The real way to do this, because ripple voltage is not sinusoidal, is to use an oscilloscope, particularly if you want the peak values.
What is ac ripple neutralizer?
it is nothing but ac ripple neutralizer
What is ripple factor?
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) valueof the ripple voltage to the absolute value of the dc component of the output ...
Unit of ripple factor?
Ripple, in DC power supplies, is technically unitless. Ripple voltage is specified in Volts/Volt, or a percentage. For example, a 12VDC power supply with 120mV (pk-pk) of ripple voltage is (0.12/12) = 1% ripple voltage.
What cause excessive ripple voltage from a power supply.?
I think the cause of ripple voltage would be from a bad ground or capacitve voltage.
Why does low pass RC circuit filter the voltage?
In a DC power supply, a low-pass RC filter is typically used to "filter the voltage" by reducing or eliminating any remaining ripple. This works because such ripple has frequency components over 0 Hz (ripple is essentially an AC component with an offset), which are suppressed by the low-pass filter.
