A simple method for a capacitor’s ESR measurement
CitationAsadi, F. ve Abut, N. (2017). A simple method for a capacitor’s ESR measurement. Power Electronics.
Capacitors are classified according to their dielectric’s type. Electrolytic capacitors are popular in power electronic circuits, due to their high volumetric efficiency and excellent price performance ratio. Unfortunately, their characteristics change with operating frequency, whereas an ideal capacitor’s impedance decreases with frequency. But, in the real world this is not seen in the laboratory. Increasing frequency up to a certain point leads to the expected impedance reduction but increasing frequency causes the impedance to increase, i.e., it acts like a resonance circuit. To model the behavior of an actual capacitor requires the addition of extra elements to the capacitor model. ESR is actually the resistance that a capacitor shows in the border between capacitor-like behavior and inductor-like behavior, i.e., resistance at the resonance frequency.
