II类MLCC大信号激励损耗的ESR建模

Multilayer ceramic capacitors (MLCCs) with ferroelectric Class II dielectrics enable extremely high volumetric capacitance density, and are therefore preferred in high-power-density power conversion. These MLCCs, though, suffer from a nonlinear dielectric constant and substantial low-frequency, large-signal excitation losses. Previously, a Steinmetz-parameter-based loss model accurately described ...
