Silicon carbide (SiC) devices can significantly increase power efficiency, temperature reliability, capacity, and density because of their outstanding characteristics. Nevertheless, in the bridge-leg configuration a converter, high-speed switching capability SiC mosfets is often restricted by coupling noise between high-side mosfet low-side mosfet. The caused high ${dv/dt}$ ${di/dt}$ transient will loss risk breakdown. In order to completely take advantage superior feature mosfets, novel...
The wireless power transfer (WPT) method for electric vehicles (EVs) is becoming more popular, and to ensure the interoperability of WPT systems, Society Automotive Engineers (SAE) established J2954 recommended practice (RP). It includes powering frequency, electrical parameters, specifications, testing procedures, other contents EV WPT. Specifically, it describes ranges self-inductances transmitting coil, receiving coupling coefficient (k), as well impedance matching values system....
The structure of self-organized quantum wires buried at the interfaces a SiGe/Si multilayer is investigated by grazing incidence small-angle x-ray scattering. A nearly periodic distribution wires, well described short-range ordering model, gives rise to intensity satellite maxima in reciprocal space. shape wire cross section determined from heights these maxima, and analysis reveals that conventional step-bunching model not sufficient explain shape.
This paper studies the electromagnetic properties of defected ground structure (DGS) with von Koch snowflake fractals. First, fractal is employed in dumbbell shaped DGS, and we have discovered that it has characteristics a low-pass filter out-of-band rejection increases iterations. In consideration fabrication accuracy performance, third iteration been adopted. Based on this structure, designed narrow-band wide-band to verify our theory. From simulated measured results, can see level greatly...
Far-end crosstalk (FEXT) can be a problem in the design of printed circuit boards (PCB) for incoming fifth generation double data rate (DDR5). In this paper, FEXT mitigation method is proposed. This adds an additional layer homogeneous dielectric substrate with or without metal to make transmission line more homogeneous. Therefore, capacitive cancel out inductive at far end. our research, lines tabbed routing are analyzed and simulated. Finally, frequency-domain time-domain simulated results...
Abstract A simple wideband planar antenna with a separated fence structure is presented in this study for 4/5G base station application. To improve the front‐to‐back ratio (FBR) and half‐power beamwidth (HPBW) of proposed antenna, five parasitic structures are designed.
