Best capacitors for power supplies update
Electrolytic capacitors types for power supplies come and go. They attend different demands than stages interface or other more subtle applications. Some are large and recommended for main raw filtering, usually before regulators. Some are small and have to take care of smaller currents. Raw...
Is it safe to add a big capacitor in parallel to a power supply output?
I have an application which uses a 1000W standard PC power supply, drawing continuously around 300W. However, sometimes there are short power surges of ~800W or more, which I believe triggers the p... $begingroup$ Supercapacitors have a very low voltage limit. Supercapacitors have a very low voltage limit.
What are some reasons to connect capacitors in series?
On some power supply front-ends (AC/DC conversion) with a voltage doubler the capacitors are in parallel at low voltage and in series at high voltage. This works out well since for a constant power out the current is double at the lower voltage.

I have seen circuit diagram in analog devices application note which shows that both supply rails have a 1uF and 0.1uF capacitor for dual supply opamp but only the Vcc has them in a single supply opamp. Why are decoupling capacitors used on both supply rails in
What Are Decoupling Capacitors?
In power supplies, decoupling capacitors are strategically placed near the power pins of integrated circuits (ICs) or other sensitive components. The decoupling capacitors are connected in parallel to the power supply lines and act as a local energy reservoir that can quickly supply or absorb current as needed (Figure 1).

Capacitors Guide: Types, Uses and Choosing the Right One
When a capacitor is connected to a voltage source, like a power supply or battery, it causes a voltage difference between the plates, creating an electrical field. How does this happen? Electrons in the conductor connected to the negative terminal of the voltage source are repelled and flow onto one of the conductive plates, giving it a …
