6 FAQs about [Dynamic analysis with capacitors]

What are dynamic capacitance characteristics of a MOSFET?

The dynamic capacitance characteristics of a mosfet are closely related to the switching behavior of the circuit and EMI generation. Therefore, for EMI analysis and to control power conversion systems, the capacitances of the mosfet s have to be accurately known. The capacitance of a mosfet changes depending on the dc bias voltage.

Can a dynamic equivalent circuit be used to model supercapacitors?

The aim of this study was to demonstrate that the dynamic equivalent circuit can be used to model the behaviour of supercapacitors if one allows for an interpretation in terms of a distribution of relaxation times.

How to determine dynamic capacitance of a half-bridge MOSFET?

By changing the terminal connection of the half-bridge mosfet , the dynamic capacitances were obtained through two-port S-parameter measurement. The proposed method was verified through simulation and experiment, and a switching test was performed for EMI analysis.

How can a supercapacitor be interpreted in a consistent manner?

Such a model can be used to explain the most common features of a supercapacitor in a consistent manner. In the time domain, it is shown that the time-dependent charging rate and the self-discharge of a supercapacitor can both be interpreted in this model with either a few or a continuous distribution of relaxation times.

Can supercapacitors explain long-term dynamics?

Supercapacitors are often modelled using electrical equivalent circuits with a limited number of branches. However, the limited number of branches often cannot explain long-term dynamics, and one therefore has to resort to more computationally challenging basic models governing diffusion and drift of ions.

How do you determine the optimal capacitor energies?
