Ion-liquid based super-capacitors with inner gate diode-like separators
, 2019 We demonstrate that the capacitance of ionic-liquid filled supercapacitors is substantially increased by placing a diode-like structure on the separator membrane. We call the structured separator: gate, and demonstrate that the order of a p-n layout with

An Asymmetric Switched Capacitor Multilevel Inverter With Component Reduction [PDF]
IEEE Access, 2019 This paper proposes a new switched capacitor (SC-Type) inverter for asymmetrical multilevel inverters (MLIs) with fewer components. In order to balance the voltages of the capacitors, the proposed topology uses a special method to charge/discharge the capacitors.

Prediction of Gap Asymmetry in Differential Micro Accelerometers
Sensors, 2012 Gap asymmetry in differential capacitors is the primary source of the zero bias output of force-balanced micro accelerometers. It is also used to evaluate the applicability of differential structures in MEMS manufacturing.

A High Step-Up Interleaved Current-Fed Resonant Converter for High-Voltage Applications
IEEE Access, 2022 A current-fed LLC resonant converter is proposed for high-voltage and high-power applications. Here, a two-phase interleaved structure is used in the input stage under the continuous conduction mode (CCM) to effectively reduce the input current and ...

Charging Ultra-nanoporous Electrodes with Size-asymmetric Ions Assisted by Apolar Solvent [PDF]
, 2016 We develop a statistical theory of charging quasi single-file pores with cations and anions of different sizes as well as solvent molecules or voids. This is done by mapping the charging onto a one-dimensional Blume–Emery–Griffith model with variable ...

Monitoring the length change of Ni@C composite electrodes during charging/discharging processes
Electrochemistry Communications, 2019 The iterative volume change of electrode materials during electrochemical charging/discharging processes could generally result in the performance degradation of electrochemical capacitors. This work investigates the mechanical stability of the electrode

Cost-Effective and High-Efficiency Variable-Speed Switched Reluctance Drives With Ring-Connected Winding Configuration [PDF]
, 2019 This paper presents a novel converter topology for six-phase switched reluctance motor (SRM) drives, which reduces the number of switches and diodes by half, compared with the conventional asymmetric half-bridge converter, but needs no additional energy ...
