Development and characterization of a new solid polymer electrolyte for supercapacitor device
(Hindawi, 2023)
In this study, solid polymer electrolytes (SPEs) are based on methylcellulose (MC) used as a polymer host and sodium iodide (NaI) as a dopant. The SPE films are developed using different contents of ethyl carbonate (EC) ...
New modified carrier-based level-shifted PWM control for NPC rectifiers considered for implementation in EV fast chargers
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)
In this study, the aim is to evaluate three-phase (3ϕ) AC/DC neutral point-clamped (NPC) power factor-corrected (PFC) multilevel converter performance for electric vehicle (EV) fast chargers. Power factor correction for ...
The role of intrinsic atomic defects in a Janus MoSSe/XN (X = Al, Ga) heterostructure: a first principles study
(Institute for Condensed Matter Physics, 2023)
The interactions between different layers in van der Waals heterostructures have a significant impact on the electronic and optical characteristics. By utilizing the intrinsic dipole moment of Janus transition metal ...
Comparative study of single-phase multilevel cascaded transformerless inverters with different modulation methods
(Elsevier, 2024)
This paper presents an in-depth exploration of a single -phase multilevel cascaded H5 (CH5) transformerless inverter employing both phase-shifted PWM (PS-PWM) and level-shifted PWM (LS-PWM) methodologies. A comparative ...
Experimental and simulated investigation of a single-phase transformerless H5 inverter topology
(Tafila Technical University, 2024)
This paper aims to simulate and experimentally apply a single-phase transformerless H5 inverter topology. The H5 inverter topology is simulated in MATLAB/Simulink environment as both off-grid and grid-connected. The ...
Efficient Tm:YAG and Tm:LuAG lasers pumped by 681 nm tapered diodes
(OSA - The Optical Society, 2019)
In this paper, we present highly efficient continuous-wave (cw) laser operation of Tm:YAG and Tm:LuAG lasers pumped by high-brightness red tapered diodes. The single-emitter tapered diode lasers (TDLs) provide up to 1 W ...
