Capacitor coupled output amplifiers

Amplifier gain stages for audio frequencies need isolation between output and input. Capacitors work fine in this application but one can also use transformers. TCdriver is correct that amp outputs need to limit DC current in the output to prevent heating in the speaker drivers. Tube amps do this with an output transformer. Big capacitors do it

A variable air capacitor (Figure (PageIndex{7})) has two sets of parallel plates. One set of plates is fixed (indicated as "stator"), and the other set of plates is attached to a shaft that can be rotated (indicated as "rotor"). By turning the shaft, the cross-sectional area in the overlap of the plates can be changed; therefore, the capacitance of this system can be tuned

6 FAQs about [Capacitor output capacity]

What is the purpose of capacitors on the output of a power supply?

One purpose of capacitors on the output of a power supply is to attenuate undesired electrical noise as the power is delivered to the external load. Another purpose of capacitors on the output of a power supply is to minimize the change in output voltage due to the occurrence of load current transients.

How do output capacitors work?

Comparatively high currents flow suddenly and repeatedly. The output capacitor is repeatedly charged and discharged according to the output ripple voltage, which is centered on the output voltage. From here, we discuss output capacitors. The following three factors are important when selecting the output capacitor.

How to select an output capacitor?

・When selecting an output capacitor, the rated voltage, rated ripple current, and ESR are important parameters. ・In addition to smoothing and regulation, output capacitors are also closely related to the output ripple voltage. In succession to selection of inductors, we turn to a discussion of capacitor selection.

What parameters should be included in the selection of output capacitors?

The most important parameters are the magnitude of the load transient (ΔI) and the distributed bus impedance to the load. The selection of the output capacitors is determined by the allowable peak voltage deviation (ΔV). This limit should reflect the actual requirements, and should not be specified lower than needed.

What are the important elements in designing output capacitors?

Important elements in designing output capacitor are rating voltage, ripple rating current, and ESR (equivalent series resistance). Ripple current and voltage impressed to the capacitor must be less than the maximum rating. ESR is an important element to decide the output ripple voltage with the inductor current.

What are the characteristics of a capacitor?

A fundamental description regarding the characteristics of a capacitor is shown in equation 1. Equation 1 The current (I) into (or out of) a capacitor is equal to the value of the capacitance (C) times the change in voltage across the capacitor (dV) divided by the change in time (dt) during which the change in voltage occurs.
