Types of Battery Chargers - Simple
... These chargers can supply either a constant voltage or a constant current to the battery ... Simple AC-powered battery chargers have much higher ripple current and ripple voltage than other kinds of battery supplies ... When the ripple current is within the battery-manufacturer-recommended level, the ripple voltage will also be well within the recommended level ...
Types Of Capacitor - Electrical Characteristics - Limiting Current Loads - Ripple Current
... A "ripple current" is the RMS value of a superimposed AC current of any frequency and any waveform of the current curve for continuous operation at a specified ... power supplies) after rectifying an AC voltage and flows as charge and discharge current through the decoupling or smoothing capacitor ... The "rated ripple current" shall not exceed a temperature rise of 3, 5 or 10 °C, depending on the capacitor type, at the specified maximum ambient temperature ...
Equivalent Series Resistance - Component Models - Capacitors
... with normal aging, high temperatures and large ripple current exacerbate the problem ... In a circuit with significant ripple current, an increase in ESR will increase heat dissipation, thus accelerating aging ... Therefore polymer capacitors can handle higher ripple current ...
Capacitator - Non-ideal Behavior - Ripple Current
... Ripple current is the AC component of an applied source (often a switched-mode power supply) (whose frequency may be constant or varying) ... Ripple current causes heat to be generated within the capacitor due to the dielectric losses caused by the changing field strength together with the current flow across ... electrolytic capacitors, as well as some film capacitors have a specified rating value for maximum ripple current ...

Famous quotes containing the words current and/or ripple:

    “I” is a militant social tendency, working to hold and enlarge its place in the general current of tendencies. So far as it can it waxes, as all life does. To think of it as apart from society is a palpable absurdity of which no one could be guilty who really saw it as a fact of life.
    Charles Horton Cooley (1864–1929)

    The forest waves, the morning breaks,
    The pastures sleep, ripple the lakes,
    Leaves twinkle, flowers like persons be
    And life pulsates in rock or tree.
    Ralph Waldo Emerson (1803–1882)
