Multilayer Ceramic Capacitors (MLCCs) are of paramount importance in electronics and ferroelectric Class II dielectrics enable outstanding energy-density values. However, the non-linear dielectric constant and associated low-frequency large-signal ex

The capacitance of voltage-dependent capacitors can be defined in two ways: as “total capacitance” Ct ( v ) = Q / v and “local capacitance” Cd ( v ) = dQ / dv . The former is applicable to cases when the capacitance is measured by a charge in

A SPICE model for estimating and simulating core losses of a ferrite magnetic device is presented. The approach is based on a proposed revised generalized Steinmetz equation (RGSE) and requires only the use of the Steinmetz coefficients and core geom

A generic algebraic model of switched-resonator converters is developed and demonstrated by published and new converter configurations data. The model hinges on a newly introduced multiport global-gyrator matrix, of which the classical two-port gyrat

Applying the observed frequency dependence of the equivalent series resistance of ferroelectric-based ceramic capacitors, the value of a parallel resistor that models the losses is extracted for small signal excitation. The result is then used to dev

The feasibility of applying standard commercial ceramic capacitors (CC) for controlling a series resonant converter was examined by a simulation model that was calibrated experimentally. The study reveals that the CC could be a viable control element

A simple, user-friendly model is proposed to estimate ferrite core losses and the hot spot temperature by SPICE simulation that are based on the Steinmetz equation. The model is capable to produce, on the fly, the estimates as the operating condition
