The article discusses design of mathematical model buck and boost converter and the analysis of the optimal frequency choice of the PWM signal for IGBT. The converter is dedicated for charging and discharging of hybrid car drive super-capacitor energy storage. The main role of the converter is to optimize energy content in supercapacitor storage used to acceleration and deceleration during driv...

Nickel oxide films were prepared by electrochemically precipitating the hydroxide and heating it in air to form the oxide. The resulting oxide films behave as a capacitor. The capacitance of the oxide depends on the heating temperature, showing a maximum at 3008C. The mechanism of charge storage was studied by measuring the capacitance and surface area as a function of heating temperature, and ...

Covalent organic frameworks (COFs) are emerging materials for electrochemical energy storage. This review summarizes recent advancements in COFs as battery/capacitor electrodes, proton conducting membranes, and ion solid-state electrolytes.

In this paper, the energy characteristics of charge circuits a supercapacitor (nonlinear capacitor) and an equivalent linear capacitor from DC voltage source, which is lithium-ion battery for such storage devices, are analyzed. It established under what conditions losses electricity in nonlinear capacitors source reduced. The influence final initial voltages on similar terminals capacitance reg...

This talk provides an introduction to Content Addressable Memories (CAM), Ferroelectric memories, and Multiple-Valued Ferroelectric Content-Addressable Memories (MVFCAM). Circuit simulation results are presented for two architectures of MVFCAM. What is an associative memory? An associative memory, or a Content Addressable Memory (CAM), searches for data by content rather than by address [1-4]. ...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

Energy storage devices that provide high specific power without compromising on specific energy are highly desirable for many electric-powered applications. Here, we demonstrate that polymer organic radical gel materials support fast bulk-redox charge storage, commensurate to surface double layer ion exchange at carbon electrodes. When integrated with a carbon-based electrical double layer capa...
