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.

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

Model Predictive Control of an Asymmetric Flying Capacitor Converter
IEEE Transactions on Industrial Electronics, 2009 Multilevel converters and, in particular, flying capacitor (FC) converters are an attractive alternative for medium-voltage applications. FC converters do not need complex transformers to obtain the DC-link voltage and also present good robustness properties, when operating under internal fault conditions.

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