Mathematical Modeling of Hybrid Asymmetric Electrochemical Capacitors

Journal of the Electrochemical Society, 2014
Electrochemical capacitors may be ideal energy storage devices for applications ranging from renewable energy storage to transportation. Electrochemical capacitors are characterized by high power density and cycle life, and can be classified based on the properties of their electrodes.

Current - voltage characteristic of asymmetric ferroelectric capacitors

Journal Physics D: Applied Physics, 1996
Real ferroelectric capacitors are usually asymmetric. In this paper, the current - voltage characteristic of asymmetric Pt/Pb(Zr,Ti)/Pt (Pt/PZT/Pt) thin film capacitors is studied quantitatively by using an asymmetric totally depleted back-to-back Schottky model as well as by experiment.

Electrode-dependent asymmetric conduction mechanisms in K0.5Na0.5NbO3 micro-capacitors [PDF]

open access: yesMaterials Science in Semiconductor Processing, 2023
The ultimate performance of devices employing lead-free piezoelectrics is determined not only by the intrinsic properties of the piezo, but also by processes and materials employed to create the electric contacts. In this paper, we investigate the impact

Asymmetrical current distribution in metallized film capacitors

Journal of Applied Physics, 2004
The presence of high frequency currents in the vicinity of metallized capacitors can generate eddy currents in the metallizations, with a possible negative impact on the reliability and lifetime of these components. These phenomena are due to the asymmetrical distribution of the field lines.

Class DE Inverter with Asymmetric Shunt Capacitors

2007 IEEE International Symposium on Circuits and Systems, 2007
This paper presents a class DE inverter with asymmetric shunt capacitors. Generally the shunt capacitors of class DE inverter are equally given to the two switching devices. The input current from the dc power source flows into the upper shunt capacitor during the dead time.
