In a way, decoupling capacitors act as a very small, local power supply for ICs (almost like an uninterruptible power supply is to computers). If the power supply very temporarily drops its voltage (which is actually pretty common, especially when the circuit it''s powering is constantly switching its load requirements), a decoupling capacitor can briefly supply

Hold-Up time is defined as the duration of time that a power supply''s output will remain within regulated limits following a loss of input power. For example, for a 5V output power supply with a ±10% (±0.5V) regulated output, the hold-up time is measured from the time the input is turned "OFF" to the time when the output voltage drops

The input of switching power supply circuits requires input capacitors usually referred to as CINs. The role of input capacitors is to allow ripple currents from discharges due to the switching of power transistors and charges from input power supplies, ripple currents due to fluctuations in input voltage, etc., to stabilize the input

The major advantage of the switch mode power supply is its higher efficiency, compared to standard linear regulators, and this is achieved by internally switching a transistor (or power MOSFET) between its "ON" state (saturated) and its "OFF" state (cut-off), both of which produces lower power dissipation. This means that when the

The usable energy in the single string of eight (in series) is W = 1*[(10F/8)/2*((2.7V*8)2-6V2)] = 269.1J Since both capacitor banks store the same total energy, the string with lower voltage has a greater percentage of charge wasted/unusable. In this case, the higher string voltage is preferable to fully utilize the SCs.

In switching power supply designs, the input voltage is no longer reduced; instead, it''s rectified and filtered at the input. Then the voltage goes through a chopper, which converts it into a high-frequency pulse train. Before the voltage reaches the output, it''s filtered and rectified once again.

It depends on your circuit (which you haven''t shown) but remember that what takes a long time to discharge takes a long time to recharge. It''s a general question. Also, when a power supply is capable to meet the worse case of the current, usually it is able to charge its capacitors too.
