Title: Simulation Of The Mathematical Modeling Of A Double-Layer Capacitor Using PSIM Software

Keywords: Double-Layer Capacitor, Energy Storage, Three RC Branch Equivalent Circuit, Terminal Behavior, Carbon-Based DLC

The double-layer capacitor (DLC) is a low voltage device exhibiting an extremely high capacitance value in comparison with other capacitor technologies of similar physical size. It’s also a promising device for certain power electronic application as energy storage. A three-RC branch equivalent circuit was used to characterize its terminal behavior and the equivalent circuits result are simulated using PSIM to provide the power electronics engineers a model for the terminal behavior of the DLC. An elaborated method to identify the circuit parameters was also presented here. The measurements of carbon-based DLC’s showed that the simulated equivalent circuit response is similar with the experimental results.
