A New Model of Ultracapacitors Based on Fractal Fundamentals

Abstract EN

An intuitive model is proposed in this paper to describe the electrical behavior of certain ultracapacitors.

The model is based on a simple expression that can be fully characterized by five real numbers.

In this paper, the measured impedances of three ultracapacitors as a function of frequency are compared to model results.

There is good agreement between the model and measurements.

Results presented in a previous study are also reviewed and the paper demonstrates that those results are also consistent with the newly described model.
