Basic Calculation of a Boost Converter''s Power Stage (Rev. D)
The forward current rating needed is equal to the maximum output current: I =I. F OUT(max) (7) I. F = average forward current of the rectifier diode I. OUT(max) = maximum output current necessary in the application Schottky diodes have a much higher peak current rating than average rating. Therefore the higher peak current in the system is …

How can I determine the current rating of a capacitor?
Most capacitors don''t actually have a "current" rating, since that doesn''t make much sense. You can''t put a sustained current through a capacitor anyway. If you tried, its voltage would rise linearly, and then you''d get to the voltage limit where you''d …
Electrolytic capacitor rms and peak current
Can electrolytic capacitors can have higher peak current than their max RMS or ripple current ratings as long as RMS current is below the specified current value? Such as a capacitor with a rating of 1.5amp RMS …

How do I know the maximum voltage that a capacitor …
Capacitors store energy. The voltage depends upon the amount of charge and the size of the capacitor. (Q = CV, Energy stored = 0.5CV^2). If you connect a resistor across the terminals of a charged capacitor an initial …
15.2 Simple AC Circuits
The vertical axis on a phasor diagram could be either the voltage or the current, depending on the phasor that is being examined. In addition, several quantities can be depicted on the same phasor diagram. For example, both the current i R (t) i R (t) and the voltage v R (t) v R (t) are shown in the diagram of Figure 15.6(b).(b).
23.11 Reactance, Inductive and Capacitive
The current becomes positive after point b, neutralizing the charge on the capacitor and bringing the voltage to zero at point c, which allows the current to reach its maximum. Between points c and d, the current drops to zero as the voltage rises to its peak, and the process starts to repeat.
Capacitor operating current rating? | All About Circuits
As Max stated, capacitors do have ESR. This dissipates power when charging and discharging the capacitor. This causes heating of the capacitor and it''s the maximum capacitor operating temperature which limits how much current and the frequency of the current pulses that the cap can tolerate.
15.3: Simple AC Circuits
where (V_0) is the peak voltage in an ac system. The rms current appears because the voltage is continually reversing, charging, and discharging the capacitor. If the frequency goes to zero, which would be a dc voltage, (X_C) tends to infinity, and the current is zero once the capacitor is charged.

A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region can either be a vacuum or an electrical insulator material known as a dielectric. Examples of dielectric media are glass, air, paper, plastic, ceramic, and even a semiconductor depletion region chemically identical to the conductors. From Coulomb''s law a charge on one conductor wil…
