What is low ripple power supply?
When an alternating current is converted to direct current, small voltage variations at the supply frequency are difficult to smooth out, or filter, completely. In the case of power supplies operated from the 60-Hz power line, the result is a low-frequency variation in the power supply's output called ripple voltage.
What is good ripple for power supply?
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.
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.
What is ripple in power system?
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.
