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.

A DC link is typically connected to a rectifier (or other DC source such as a battery) and an inverter. A DC link capacitor is used as a load-balancing energy storage device. This capacitor is connected in parallel between the positive and the negative rails and helps prevent the transients on the load side from going back to the input side.

A: The energy stored in a capacitor is half the product of the capacitance and the square of the voltage, as given by the formula E = ½CV². This is because the energy stored is proportional to the work done to charge the capacitor, which is equal to half the product of the charge and voltage.
