### Sociology final exam multiple choice

Mar 11, 2015 · The answer obtained is the percent ripple, which is defined as the r.m.s. value of the output ripple voltage, times 100, divided by the d.c. voltage. An additional scale for critical inductance is placed just beside the resistance scale.

A voltage regulator operates on a different principle than a filter, which is essentially a voltage divider that shunts voltage at the ripple frequency away from the load. Rather, a regulator increases or decreases current supplied to the load in order to maintain a constant output voltage.

What parameters determine the frequency of a power supply’s ripple voltage? ﬁle 02014 Question 8 The ripple frequency of a half-wave rectiﬁer circuit powered by 60 Hz AC is measured to be 60 Hz. The ripple frequency of a full-wave rectiﬁer circuit powered by the exact same 60 Hz AC line voltage is measured to be 120 Hz. The amount of voltage ripple seen at VOUTis inversely proportional to the capacitor value and proportional to ESR. We can make C very large, so the ultimate limit is the ESR. The input filter capacitor will reduce the noise injected onto the V INline which can interfere with other parts of the system.

Ripple = (RMS of ripple voltage/average DC output voltage). Ripple is an AC voltage superimposed on top of the DC output voltage. Every type of rectifier circuit will have some amount of ripple present on the output.
