About Photovoltaic Energy StorageThe coupling capacitor is a general parallel plate capacitor. Its construction is very simple. Just a dielectric is present in between the parallel plate capacitors. This coupling capacitor is good at obtaining final output as AC signals. There exist decoupling capacitors as well in which the output generated is consisting of DC …
About Photovoltaic Energy StorageOver the years, with much experimenting and listening, I have found that a very major part of amplifier sound quality is directly due to the input coupling capacitors used. This is equally true for the output coupling capacitors of the preamp. Certainly the designer of the circuitry must do the job properly, but given that this is accomplished, and …
About Photovoltaic Energy StorageThe function of the output coupling capacitors is to keep the DC voltage from reaching the speaker. This is very common for solid state amplifiers that use a single supply rail for the output stage. The capacitance is high enough to couple all the audio frequencies to the loudspeaker. A smaller value capacitor would limit the low frequencies.

About Photovoltaic Energy StorageSo, both coupling and blocking capacitors are the same - a charged capacitor acting as a constant voltage source. But in the first case it is connected in series while in the second - in parallel to another voltage source. And both coupling and blocking capacitors do the same - they keep the voltage across themselves constant.
