Determining the Dependence of the Capacitance of Ferro-Ceramic Capacitors on Voltage by the Pulse Discharge Method

Resumo

An analytical model of the dependence of the capacitance of ceramic capacitors on applied voltage has been substantiated, both theoretically and experimentally. A method of determining the parameters of the analytical model was developed on the basis of an exact solution of the nonlinear differential equation of capacitor discharge. Experimental data for ferro-ceramic multilayered capacitors is provided. Correspondence of the results of the proposed method with data from direct measurements by an RLC measuring instrument and information specified by the capacitor manufacturer, throughout the working voltage range, is noted.
