What is the function of a filter capacitor in a power supply?
Mudlimeson
A: The function is to change the pulsating DC into a smooth DC by removing the peak changes. The results are very little AC variation riding on top of the DC value or simply referred as ripple.

Power supply makes a whistle noise and computer doesn't turn on?
This is caused by a blown capacitor. The electrolyte in the capacitor is boiling, and the capacitor has opened to vent the excess pressure. You will need to purchase a new power supply or have a computer technician do it for you.
What is the main function of PC power supplies boxes?
The PC power supply box's function is to supply the computer with power. Without the PC power supply box, the computer would not be able to turn on and off.
Difference between linear power supply and switch mode power supply?
a linear power supply the noise or ripple can be reduced to mv. However it is bulky heavy and inefficient A switching power supply it is easier to filter its output but the hi frequency noise and spikes are not that ease to get rid off. The weight and size can be greatly reduced and the efficiency greatly improved
What is psu in system unit and its function?
A PSU in a system unit is the power supply unit. It provides well-regulated power for the computer and its peripherals.
What is the function of a DC power supply?
By Khalid BetaniDirect current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.So the function of a DC Power Supply is to provide Direct current to various accessories of computer such as Hard Disk, Ram, Picture Tube or LCD, Mother Board, CD Rom/DVD Rom, etc, so that they function properly.
What type of capacitor is often used in power-supply circuits to filter the rectified AC?
The electrolytic capacitor is most often used in power supply circuits to filter the rectified AC.
What is the function of capacitor across the supply to the fluorescent lamp when it is used?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What is the function of the capacitor in the fluorescent lamp?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What type of function of capacitor in dc power supply?
It filters ac to pure dc
Why you use capacitor as a filter in power supply?
capacitor acts as a small battery ,during rectification ac to dc it gets some blank space (no current) to fill this current from capacitor is used.
What is the use of harmonic filter in capacitor bank?
harmonic filter capacitor is used to filterize the unwanted heat created by a certain component like power supply. harmonics are voltage or currents that operates a certain frequency. john
Why it is necessary to connect ceramic disc capacitor across filter capacitor?
The filter capacitor has inductance and is therefore not very responsive to short term transients, i.e. fast rising or falling current edges. The ceramic disk capacitor, on the other hand, has very little inductance, and therefore is very responsive to short term transients. It is normal "best practices" to connect a small ceramic disk capacitor at each IC's Vcc terminal while also using bulk capacitance in the power supply and at various other places. For the same reason, you want a ceramic disc at the main filter capacitor in the power supply.
What is a smoothing capacitor?
A Smoothing Capacitor is a capacitor which helps to smooth out fluctuations that may exist on a power supply line.
Which filter do you use to remove pulsations from a power supply output?
There is no answer to this. If a power supply pulsates, what frequency, etc. If a power output needs filtering there are oodles of ways to do it depending on the desired result and the starting conditions. A starting point is a big capacitor.
What is held by power supply capacitor?
Capacitor store electrostatic energy in form of electric field.
