Some articles on ripple current, current, ripple:

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 temperature ... 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 ...
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 the slightly resistive ... as well as some film capacitors have a specified rating value for maximum ripple current ...
Types of Battery Chargers - Simple
... 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 ...
Equivalent Series Resistance - Component Models - Capacitors
... 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 ...

Famous quotes containing the words current and/or ripple:

    A man is a little thing whilst he works by and for himself, but, when he gives voice to the rules of love and justice, is godlike, his word is current in all countries; and all men, though his enemies are made his friends and obey it as their own.
    Ralph Waldo Emerson (1803–1882)

    The pure serene of memory in one man,—
    A ripple widening from a single stone
    Winding around the waters of the world.
    Theodore Roethke (1908–1963)
