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.

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.
Multiple energy-storage elements resonant power converters (x-Element RPC) are the sixth-generation converters. According to the transferring, power becomes higher and higher, traditional methods are hardly satisfied to deliver large power from source to final actuators with high efficiency.
The controllable component energy constraint of the energy storage element ranges between the minimum and maximum output, and the energy constraint needs to satisfy the capacity constraint of the energy storage at each moment and maintain the same power state at the end of the period as at the beginning.
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.
For example, the fourth order RTN network shown in Fig. 8 is a well-known topology called the LCLC tank network , whereby this topology incorporates the properties of both of the most popular three-elements network which are LCC and LLC, and thus exhibits their limitations.
