A PFC converter topology based on active power decoupling circuit with asymmetric small split capacitors

open access: yesElectronics Letters, 2022
A novel active power decoupling converter (APDC) applied in power factor correction (PFC) converter is proposed, which overcomes the problem that the DC‐link voltage ripple of small capacitor PFC converters depend heavily on the consistency of capacitors.

Three-Phase Trinary Asymmetric Multilevel Inverter With Single DC Source and Open-Loop Control

open access: yesIEEE Open Journal of Industry Applications, 2021
A three-phase trinary-asymmetric cascaded H-bridge multilevel inverter topology with single dc source per phase is presented in this paper. Only one of the H-bridges (called Main bridge) is fed from a dc source and all others (called auxiliary bridges ...

Improved Symmetry of Ferroelectric Switching in HZO Based MFM Capacitors Enabled by High Pressure Annealing

open access: yesIEEE Journal of the Electron Devices Society, 2022
The interface difference between HZO and the upper and lower electrodes induced by the sequence of the process flow could lead to the general asymmetry in the structure and performance of metal-ferroelectric-metal (MFM) capacitors, which may cause ...

Radiation-induced separation and accumulation of electric charge in supercapacitors [PDF]

open access: yesNuclear Energy and Technology, 2018
In current sources with a radioactive isotope (CSRI), nuclear energy is directly converted into electricity due to the separation of electric charges during the decay of radioactive isotopes. It was previously shown that asymmetric supercapacitors can be

General hybrid asymmetric capacitor model: Validation with a commercial lithium ion capacitor

open access: yesJournal of Power Sources, 2019
Modelling and numerical simulations play a vital role in the design and optimization of electrochemical energy storage devices. In this study, a general physics-based model is developed to describe Hybrid Asymmetric Capacitors (HACs). A one-dimensional cell is constructed with one faradaic electrode, a separator and a capacitive electrode. The model is

A Novel Dual-Mode Dual-Band Bandpass Filter Based on a Single Ring Resonator [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2020
In this paper, a dual-mode bandpass filter that operates in two different bands is proposed. A circular patch with a small circular hole is set as the basic resonator, and, as the circular hole moves, the linewidth of the ring resonator becomes non ...
