Capacitor Ripple Current. Ripple current is just the AC parts of a voltage source applied to the capacitor. The thing you need to know is that the capacitor will generate heat due to the dielectric losses caused by the ripple current. Therefore, its important that this heat generated doesn''t get too high that it damages the capacitor.
This family of capacitors is designed for high-current applications, such as (1) SCR commutation, (2) snubbers for SCRs, GTOs and other power semiconductors, and (3) for any other circuits where the combination of frequency and voltage results in high RMS currents. An Application Note is provided to assist in the proper use of these devices. It is strongly recom- …
We discuss extensions to Verilog-A that address compact modeling needs. It reviews compact modeling and analog circuit simulation, and then presents a simple Verilog-A compact model for a capacitor.
Put another way, current through a capacitor is inherently AC. Capacitors do often have a ripple current spec. Capacitors designed to be used in applications where this matters, like switching power supplies, will have a ripple current spec. Check out the Panasonic FK series, for example. These are designed for particularly low ESR (for ...
V1 will be a ZVS system that is out of scope of the question. Accordint to my computations and confirmed with simulations, the current into C1 will be a sine of 56A RMS at a frequency of 100kHz. 70V pk-pk. I may consider replacing C1 by several capacitor to reduce the current rating of each of them. I may also consider adding a radiator if needed.

capacitor charge cycle, the current through the diode is relatively high and the equivalent resistance of the diode is low, allowing the capacitor to charge quickly. As the capacitor be-comes charged, the current will decrease steadily and the diode resis-tance will increase, limiting the noise amplification automatically. Typically, the diode can be a small-signal diode, such as …
As the lumped model suggests, real-world capacitors behave like series-connected LCR circuits. As the frequency of an applied AC voltage increases, the inductive reactance of the ESL increases to a point at which it is equal to the capacitive reactance of the device, and the capacitor behaves as a resistor. At frequencies above this point, the …
