Power Relationships for Evaluating the Efficiency of Dielectric Capacitors
Power relationships for the macroscopic electrodynamics of a dielectric are considered taking into account the frequency dispersion of dielectric permeability caused by relaxation polarization processes. General expressions for the densities of power flows and discharge energies are obtained for the case when the relaxation process has an arbitrary spectrum. An example of assessing the power efficiency of a dielectric for capacitive energy stores is given.
