The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.

In the cascaded multilevel inverter with hybrid energy sources, the …
However, elements such as capacitors and inductors have the property of being able to store energy, whose V–I relationships contain either time integrals or derivatives of voltage or current. As one would suspect, this means that the response of these elements is not instantaneous. Download to read the full chapter text.

The energy of a capacitor is stored within the electric field between two conducting plates while the energy of an inductor is stored within the magnetic field of a conducting coil. Both elements can be charged (i.e., the stored energy is increased) or discharged (i.e., the stored energy is decreased).
