6 FAQs about [Input energy storage capacitor selection]
How to select input capacitors?
The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.
What is an energy storage capacitor?
Capacitors for Energy Storage Applications Energy storage capacitors can typically be found in remote or battery powered applications. Capacitors can be used to deliver peak power, reducing depth of discharge on batteries, or provide hold-up energy for memory read/write during an unexpected shut-off.
How do I choose a capacitor for an output filter?
For an output filter you choose a capacitor to handle the load transients and to minimize the output voltage ripple. The equation in Figure 3 shows the equation to determine the input current RMS (Root-Mean-Squared) current the capacitor can handle.
What parameters should be included in the selection of output capacitors?
The most important parameters are the magnitude of the load transient (ΔI) and the distributed bus impedance to the load. The selection of the output capacitors is determined by the allowable peak voltage deviation (ΔV). This limit should reflect the actual requirements, and should not be specified lower than needed.
How to choose a capacitor?
Based on the input voltage, the input current RMS current, and the input voltage peak-to-peak ripple you can choose the capacitor looking at the capacitor datasheets. It is recommended to use a combination of Aluminum Electrolytic (AlEl) and ceramic capacitors.
