Özet
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.[1] 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.
