Summary: Some multifunction decoders support an additional external energy storage module to provide backup power when the electrical supply from the rails is interrupted by dirt, bad contact, insulated frogs, etc.This may prevent a locomotive from stalling when travelling over dirty track or turnouts with large plastic frogs, especially at low speed.
Engineers can choose between batteries, supercapacitors, or “best of both” hybrid supercapacitors for operating and backup power and energy storage. Many systems operate from an available line-operated supply or replaceable batteries for power. However, in others, there is a need in many systems to continually capture, store, and then deliver energy

Storage capacitors supply a brief, high-power burst of energy to the load, but are then allowed to slowly recharge over a much longer time period. Their benefits generally include a lower average input current, which eases the requirements on the input source and reduces the size of the converter''s power stage.
The energy delivered by the defibrillator is stored in a capacitor and can be adjusted to fit the situation. SI units of joules are often employed. Less dramatic is the use of capacitors in microelectronics to supply energy when batteries are charged (Figure (PageIndex{1})). Capacitors are also used to supply energy for flash lamps on cameras.
With their ability to store and release energy quickly, capacitors play a crucial role in power conditioning, energy efficiency, and the integration of renewable energy sources.

Power supply capacitors are often subjected to voltage surges and rapid switching, which can induce premature failure. The implications of capacitor failures in PCBs are far-reaching, ranging from minor signal degradation to complete system breakdown.
The capacitor is trying to keep the voltage at 20V even though you turned it off. If there were an actual load on this power supply, the load would instantly consume this buffer of energy. However, since there is no load (or the loads are switched off), the capacitor's charge just sits there, waiting, oblivious that you have turned off the power.
Capacitors are vital in power supply regulation and signal integrity within printed circuit boards (PCBs). Power supply capacitors are often subjected to voltage surges and rapid switching, which can induce premature failure.
Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
Mica and tantalum capacitors are more likely to fail in the early period of use (early failure), while aluminum electrolytic capacitors are more likely to experience wear-out failure due to aging use. In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal.
It's a capacitor, which is like a buffer. It job is to smooth out the DC power by resisting changes in voltage. The capacitor is trying to keep the voltage at 20V even though you turned it off. If there were an actual load on this power supply, the load would instantly consume this buffer of energy.
