6 FAQs about [Independent energy storage element]

What are a-type energy storage elements?

Energy storage elements in which the stored energy is a function of the across-variable are defined to be A-type elements, and are collectively designated as generalized capacitances. All A-type energy storage elements have constitutive equations of the form: ()designates a single-valued, monotonic function.

What is a modulated energy storage element?

The reason for this restriction is that a modulated energy-storage element would mean that the total energy in a system would be a function of the modulating input or set of inputs. Consequently, the total energy in the system would not be equal to the net power flow in across the system boundaries..

What is an example of a constraint in energy storage?

In the energy storage elements the constraint is expressed as a differential or integral rela- tionship, that defines the element as having integral or derivative causality. For example, a mass element m has an elemental relationship that is normally written in the form = m .

Is energy storage a static or memory-less function?

Note that although we will use energy storage elements to describe dynamic behavior, this constitutive equation is a static or memory-less function. The constitutive equation permits us to evaluate the generalized potential energy, Ep For this element, potential energy is a function of displacement alone.

Why is Q a generalized potential energy storage element?

It is a generalized potential energy storage element. The displacement, q, plays the same role as the specific entropy and specific volume do for a pure thermodynamic substance: it is sufficient to define the energy in the system. By convention we will define Ep = 0 at q = 0 as shown in figure 4.1.

Do two inductors contribute only one effective energy storing element?
