I have an AC/DC power supply circuit fitted to many machines, which are all running well within the rated power capability of the supplies. However these keep failing, every one burning out a (large) electrolytic capacitor (after say 1 years'' service).
Power supply capacitors enable the smoothing of rectifier outputs through energy storage. A smoothing capacitor bank is often referred to as the bulk capacitance. The energy
The easiest way to accomplish this is to add a capacitor across the power supply + and – lines. These capacitors are typically called bypass capacitors for reasons that will become clear soon. Below is an image of a schematic showing a bypass capacitor connected across the power supply lines near an IC.
capacitor To keep the impedance of the power supply line low, a capacitor with a large capacitance, low ESR, and low ESL is required. However, it is impossible to cover a wide frequency bandwidth with a single type of capacitor. In general, a capacitor with larger capacitance has a larger size, leading to a higher ESL.

When a voltage is applied across the plates, an electric field is created, allowing the capacitor to store energy. This stored energy can then be released when needed, providing various benefits to power supply systems. In
This type of power supply uses the capacitive reactance of a capacitor to reduce the mains voltage to a lower voltage to power the electronics circuit. The circuit is a combination of a voltage dropping circuit, a full-wave bridge rectifier circuit, a
My goal is to add capacitors to the Raspberry Pi power-supply. Currently I have my raspberry Pi plugged straight into a portable 5v battery, this works fine. However, I want to be able to swap from one battery to another battery (via a switch) without the Raspberry Pi turning off. Adding a buck regulator/converter will easily keep the RPi

Here the second output capacitor is 0.1 uF and it is there to deal with high frequency noise. Note that having a large capacitor on the output can cause problems. If the input was shorted so that power was removed C4 would discharge back through the regulator. Depending on voltage and capacitor size this can cause damage.

Power supply capacitors are also used by switching power supplies as the bulk capacitor and at the output for control stability and holdup. Capacitors at these locations, when also coupled with inductors, can also be configured as low pass LC filters for ripple voltage reduction on the output, and ripple current reduction on the input, and for averaging the
If the power supply to be modified had a hold-up time of 20 msec, increasing it to 200 msec would require adding the equivalent of nine more C1 capacitors. As C1 typically occupies 5 to 6% of the internal space of a power supply, this strategy would increase the size of the power supply by around 50% for the same product height.
The regulator chips on your board will be almost impossible to touch (so hot) with just around 1 watt of power dissipation. You would want to keep the input voltage as close to the output, but due to how linear regulators are designed, the input
