2. Capacitor - Wikipedia

   en.wikipedia.org/wiki/Capacitor

   The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead–acid car battery .

3. Capacitor types - Wikipedia

   en.wikipedia.org/wiki/Capacitor_types

   MKV power capacitor, double-sided metallized paper (field-free mechanical carrier of the electrodes), polypropylene film (dielectric), windings impregnated with insulating oil. A related type is the power film capacitor. The materials and construction techniques used for large power film capacitors mostly are similar to those of ordinary film ...

4. Supercapacitor - Wikipedia

   en.wikipedia.org/wiki/Supercapacitor

   The electrochemical charge storage mechanisms in solid media can be roughly (there is an overlap in some systems) classified into 3 types: Electrostatic double-layer capacitors (EDLCs) use carbon electrodes or derivatives with much higher electrostatic double-layer capacitance than electrochemical pseudocapacitance, achieving separation of charge in a Helmholtz double layer at the interface ...

   The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead-acid car battery.

6. Capacitive power supply - Wikipedia

   en.wikipedia.org/wiki/Capacitive_power_supply

   A capacitive power supply usually has a rectifier and filter to generate a direct current from the reduced alternating voltage. Such a supply comprises a capacitor, C1 whose reactance limits the current flowing through the rectifier bridge D1.

7. Electrolytic capacitor - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_capacitor

   The high ripple current across the smoothing capacitor C1 in a power supply with half-wave rectification causes significant internal heat generation corresponding to the capacitor's ESR "Ripple current" is the RMS value of a superimposed AC current of any frequency and any waveform of the current curve for continuous operation within the ...
