The Ultimate Capacitors Guide: Learn How To Use Them

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.

Understanding Current-Voltage Curves

Capacitors and inductors are fundamentally different in that their current-voltage relationships involve the rate of change. In the case of a capacitor, the current through the capacitor at any given moment is the product of capacitance and the rate of change (i.e., the derivative with respect to time) of the voltage across the capacitor.

How can a voltage across a capacitor be greater than the total voltage ...

Consider all currents zero at start, with the capacitor voltage V1. When the switch closes, a constant voltage is applied to the inductor, so current increases linearly thru the inductor. When the switch opens, this current must continue to flow instantaneously, which is thru the diode and the capacitor. This charges up the capacitor.
