Abstract
As large ceramic capacitors are entering the field of power electronics the question of the reliability of these components under operating conditions arises. In this work a Ćuk converter is proposed for stressing and lifetime testing of ceramic capacitors. A method for online measurement of capacitances in the converter is proposed. Possible applications for testing ceramic capacitors are described. The converter can be used for characterization tests. Furthermore HALT testing under increased voltage and temperature is described. Finally, a power cycling test method for ceramic capacitors is proposed.
