Capacitor with pulsating dc voltage source/current

Since the voltage/current across the capacitor is now pulsating DC in this case then how the capacitor is blocking DC while letting AC passing through the resistor? The voltage at IN is pure AC. The voltage at A is DC with the IN signal superimposed on it.

Capacitor Filter C-Filter

Capacitors serve a critical filtering function in power supplies, because an ideal power supply produces a flat DC waveform rather than the pulsating DC output of a rectifier. Most power supplies therefore utilize a rectifying circuit followed by a filter circuit that includes at least one smoothing capacitor.

A High Power Factor, Electrolytic Capacitor-Less AC-Input LED Driver Topology With High Frequency Pulsating Output Current

Light emitting diode (LED) lamps with ac-input (50 or 60 Hz) usually require an electrolytic capacitor as the dc-link capacitor in the driver circuit to: 1) balance the energy between the input and output power, and 2) to minimize the low-frequency component of the output ripple across the LEDs. The lifetime of this capacitor, however, is much shorter than that of a …

Capacitor with pulsating dc voltage source/current

$begingroup$ If the pulsating is fast enough, the capacitor would charge and discharge as if it was AC. Remember, the change in voltage is what is required for current to flow trough the capacitor, not the reversal of …

Pulsed DC

OverviewSmoothingDifference from ACUsesDangersBibliography

Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular ("flat-topped"), rather than sinusoidal, pulses. Pulsed DC is commonly produced from AC (alternating current) by a half-wave rectifier

Unregulated Power Supply Design and Tutorial

We know that a capacitor has the ability to store an electrical charge on its plates and we can use this ability to help smooth out some of the pulsating waveform. The capacitor, C1, usually called a smoothing capacitor or reservoir capacitor, becomes charged up by the current flowing through the forward biased diode during the positive half cycle.
