Charactrization of Double Layer Capacitor for Power Electronics Application
ABSTRACT
The paper [10] shows that The Double-Layer Capacitor for power appli-
cations is a new device. A simple resistive capacitive equivalent circuit
is insufficient to characterize its terminal behaviour. Based on physical
reasoning, an equivalent circuit is proposed to provide the power elec-
tronics engineer with a model for the terminal behavior of the DLC.
The equivalent model consists of three RC branches, one of them with
a voltage dependent capacitor. A method to identify the circuit pa-
rameters is presented. Measurements of carbon-based DLCs for power
applications are presented, analyzed and the equivalent circuit response
is compared with experimental results.
