To increase the power density and lifetime of power converters, the loss evaluation of passive components is crucial. The lifetime and reliability of electrolytic capacitors are strongly influenced by temperature. To calculate power loss and temperature rise, an accurate loss calculation method is proposed herein. First, a novel measuring method of the equivalent series resistance (ESR) of a capacitor by utilizing a B-H analyzer is introduced. The measured results show that the ESR of the… CONTINUE READING
