6 FAQs about [Is it better to have a larger compensation capacitor capacity ]
What is the difference between larger capacitors and smaller capacitors?
Larger caps have the tendency to respond well to DC-type signals whereas smaller value chip caps have a much higher frequency response (see Figure 1). The key is to know your environment and use a combination of smaller capacitors in parallel with the larger capacitors if possible — especially in your board development.
Why is the capacitance of a capacitor important?
The larger the capacitance of the capacitor, the lower the resonance frequency, and the smaller the frequency range in which the capacitor can effectively compensate for the current. Therefore, in order to ensure the ability of the capacitor to provide high-frequency current, the larger the capacitor, the better.
Should I use a bigger capacitor?
This is where the problem lies. All capacitors are not equal in their performance. Using a bigger cap is not always the best answer. Ideally, the capacitor should be sized for the amount of charge needed to supply transient current to the circuit for which the capacitor is filtering or decoupling.
What are the disadvantages of large-capacity capacitors?
It is true that large-capacity capacitors can bring larger loads, but subsequently, the time for capacitor charging and discharging will increase, thereby reducing the high-frequency performance of the capacitor, and large capacitors often have greater parasitic inductance. This reduces the filtering effect and affects the stability of the circuit.
Should a big filtering capacitor be bigger than a BFC?
There are cheaper ways of improving this by a factor of two than doubling the size of the Big Filtering Capacitor (BFC). The downside to a larger BFC is that it will draw larger, shorter current pulses from the input transformer and rectifier. This can cause a number of problems, though most are small, or can be mitigated.
Are all capacitors equal?
In combating this, it is often helpful to use large capacitors with large capacitance reservoirs of charge. This idea of employing a large capacitive reservoir is a great idea, provided the reservoir is capable of discharging in a fast transient environment. This is where the problem lies. All capacitors are not equal in their performance.
