6 FAQs about [Why does the filter capacitor require large energy storage]
What is the purpose of a large filter capacitor?
A large filter capacitor is used to absorb and store energy when the AC power is higher than what is needed by the DC load and to supply energy to the load when the AC power is lower than what is needed.
Why is the energy stored in the filter capacitor unusable?
In the filter capacitor, all of the energy stored--except for the little bit absorbed and released during the voltage ripple--is unusable because you need to keep the output voltage as constant as possible.
What is the role of a capacitor in a power supply?
As one of the passive components of the capacitor, its role is nothing more than the following: 1. When a capacitor is used in power supply circuits, its major function is to carry out the role of bypass, decoupling, filtering and energy storage.
