Why the Capacitor in Your Power Supply Filter is Too Big
The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. Because these capacitors have a DC value, they are actually storing a lot of energy that never gets used.
how does the filter capacitor work in a rectifier circuit?
We commonly call these capacitors "reservoir" capacitors. They act as a reserve of power during periods of no voltage in much the same way that a water reservoir can supply water during dry spells. Continuing with the water analogy, we notice that during the dry spells the water level will fall as water is consumed and this will result in falling …
What is the Use of a Decoupling Capacitor?
The X7R-type ceramic capacitor is preferred because it shows less change in capacitance as a function of DC bias voltage compared to Z5U and Y5U. Additionally, NP0 (COG) ceramic capacitors (0.1 μF or less) are also used because of their lower dielectric constant formulation and low voltage coefficient.
Reservoir Capacitor
When the supply is first switched on the voltage across the capacitor is zero (at t 0).During the first half of the first positive half cycle (t 0 to t 1) the capacitor charges up to the peak value of v i, V i.As the input voltage passes its peak value (at t 1) it becomes lower than the voltage across the capacitor, so the diode becomes reverse biased and stops conducting.
