What are the applications of capacitors in power supplies?
The most important applications for capacitors in power supplies are in energy storage, snubbering, EMI suppression, and control circuits. As we look at each area, use the accompanying chart to see how each dielectric technology competes or complements each other with respect to the application area.
Where are the capacitors located on a power supply?
When we look at almost any power supply application circuit there will be capacitors on the output of the power supply located at the load. One question often asked of power supply vendors is “Why are the output capacitors required on a power supply and how are the capacitors selected?”.
Why are capacitors placed across power supply terminals?
Based upon our discussion it should now be understood that capacitors are often placed across the power supply terminals at the load to reduce the voltage excursions caused by load current transients and the finite bandwidth response of the power supply.
How do you choose a capacitor?
Devices are sometimes banked in series and/or parallel combinations, depending on the power requirement; large can-style screw-terminal capacitors are frequently used for power levels over 10 kW. Choosing the proper capacitance value requires looking at the nominal dc voltage, allowable voltage ripple, and charge/discharge cycle time.
What equipment does a switched capacitor bank need?
In addition to the capacitors and protective equipment, a switched capacitor bank requires a switching device, control equipment, and a control power source. The control equipment for automatic switching consists of a master element, a time delay device, and auxiliary devices such as an auto-manual switch and a close-trip switch.
