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.
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.
Where is the voltage regulator in a 1991 GMC 3.8?
inside the alternator. check the fusable link at the alternator and at the starter before changing the alternator.
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
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.
Why does the battery light come on when you accelerate?
The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
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.
If its not the alternator that's bad what is it i have changed the alternator but the lights and everything are still blinking?
You need to check and make sure the alternator is charging. You could have gotten a defective one or if you got a used one it may be bad. Get a digital multimeter and with the vehicle off check the voltage at the battery. Should be 12+ volts with a charged battery. Start the vehicle and check the voltage again, should be 13-14 volts or better. If no voltage increase check the big output terminal (thick red wire usually going to it) at the alternator and see it the alternator is putting out voltage. If no voltage other than battery voltage then the alternator is not working. This is assuming that the alternator has an internal voltage regulator (most now do). Without year/make/model/engine size it's very hard to give you decent direction other that generic help :-) **I am assuming you have tested the battery**
How do you check Subaru alternator?
The easiest way to check any alternator in a car is to have the vehicle running and use a VOLT meter to read across that battery terminals. The voltage should be in the range of 13.4 volts to 14.5 volts..no lower, no higher. If either low voltage or high voltage exist, that alternator is probably defective.
Where is the voltage regulator on a 1992 Chevy Astro?
the voltage regulator is built into the alternator, check voltage at battery connections should be 14.5 volts
