摘要：

Experimental and theoretical studies are reported on the capacitance-temperature (CT) characteristics of an undoped BaTiO3 high voltage (1000 V) nonlinear ceramic disc capacitor with 3.6:1 capacitance ratio over the dc bias voltage range, for application to power electronic snubbers. CT responses for both the zero bias and 1000-V bias conditions are modeled, in terms of the polarization of permanent dipole moments. High field modeling employed a modified Langevin function, incorporating an empirical domain sensitivity parameter, together with a smeared Curie temperature. © 1990 IEEE
