Both groups converters consist of multiple energy-storage elements: two elements, three elements, or four elements. These energy-storage elements are passive parts: inductors and capacitors. They can be connected in series or parallel in various methods. In full statistics, the circuits of the multiple energy-storage elements converters are:
The two energy storage mechanical elements can have initial conditions that need to be taken into account in the analysis. A mass can have an initial velocity, which will clearly produce a force, and a spring can have a nonzero rest length, which also produces a force.
The ubiquitous capacitor is a key energy storage element in electronic systems but it turns out that there are many subtleties associated with capacitor design and operation. As an energy storage element, it is important that the capacitor retain most of the stored energy for a specified period of time.
If the inductor is subjected to an AC current, the time-averaged energy stored in the energy is calculated by substituting the effective current as follows: Notice that unlike the energy stored in the resistor, the energy stored in the adiabatic inductor can both increase and decrease. The last component we will consider is the battery.
Figure 7.8.5 7.8. 5: Voltage-current relationship for an ideal battery. Thus the electric power supplied to a battery goes into a change in the internal energy of the battery. Note that like both the capacitor and the inductor and unlike the resistor, the internal energy of an ideal, adiabatic battery can both increase and decrease.
By convention, the instantaneous electric power is positive when the current enters the system at the terminal with the higher voltage and negative when it leaves the system at the terminal with the higher voltage.

Voltage and Current | Basic Concepts Of Electricity
Voltage, as an expression of potential energy, is always relative between two locations, or points. Sometimes it is called a voltage "drop." When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current.
