Any regulated power supply needs to be designed to have low noise at the input and output to the regulator section. Getting noise low relies on selecting the right filter capacitor for your supply. Depending on the current, these capacitors can be quite large, or you may need to place a large number of capacitors in parallel.

The worst offenders are power supplies that had a fault condition before power-down - overvoltage, overtemperature, etc. - if the converter gets shut down, the primary-side bulk capacitors don''t have anything to discharge into any longer, and can take a long time to discharge to a safe voltage - especially if the power supply has PFC …
Step-By-Step Guide to Discharging Capacitors. To safely discharge the AC capacitor, follow these steps: Turn off the circuit breaker: Locate the circuit breaker that supplies power to the AC unit and switch it off. This step is crucial to prevent any power supply to the capacitor during the discharge process.
If the terminal is showing zero voltage, the capacitor is completely discharged. Is it possible that a capacitor will discharge on its own? Of course, eventually, a capacitor will discharge on its own, provided it has been disconnected from any external power or any other charging device (internal battery, for instance).

1. Power Disconnect: Before attempting to discharge the capacitor, make sure to turn off the power supply to the air conditioning unit.This can be done by switching off the circuit breaker or shutting off the power at the main electrical panel.
To discharge an AC capacitor, turn off the power supply and use an insulated screwdriver to short the terminals. An AC capacitor is an essential component in air conditioners and other electric appliances as it stores electrical energy. ... If the voltage reading shows zero, it indicates the capacitor is already discharged. If there is any ...
With the Power supply off it there will not be any stored energy in the inductors, it''s not worth mentioning, I''d be surprised that there is anything present after a few ms. given the operational modes. SO he either means capacitors or that sentence shouldn''t be there, I was giving him the benefit of the doubt. $endgroup$ –
Lets say I have 2 capacitors P and Q connected to a 9V supply. Across P there''s a resistor connected in parallel with the switch open (off position). ... to both a power supply and a resistor does the capacitor discharge ? Diagram for reference: electric-circuits; ... is it always the case that when a resistor is parallel to the capacitor even ...
A reservoir capacitor will make our DC voltage look like the chart here. Note that we still have some ripple voltage as the capacitor is discharged, but it''s certainly better than the peaks we had previously. In our circuit we are using a 220uF capacitor as our reservoir capacitor. You could use a lower or higher capacitance.
No, You can measure only the secondary (computer side) capacitors this way. The actual dangerous capacitors are on the primary (mains side) of the power supply, and can be on circuits that require at least 100V to work, meaning they stop providing power to the other side while there is still an dangerous amount of power present at the other side
You are always consuming power to charge and discharge a capacitor, this power is dissipated by the resistor. Comparing the energy stored by the capacitor this is the same as the energy dissipated on the resistance, sum of them gives the total energy supplied by the generator. Are there factors that needs to be considered?
