This paper proposes a novel packaging method for insulated-gate bipolar transistor (IGBT) modules based on the concepts of P-cell and N-cell. The reduces stray inductance in current commutation path phase-leg module hence improves switching behavior. A P-cell- N-cell-based conventional are designed. Using finite-element-analysis-based Ansys Q3D Extractor, electromagnetic simulations conducted to extract from two modules. Two prototype different designs fabricated. parasitics measured using...
To investigate the hemostatic efficacy of ultrasound in flash mode and/or microbubbles-assisted microwave coagulation for active liver hemorrhage. Thirty miniature pigs were randomly divided into five groups. Active hepatic hemorrhage was induced under guidance. Treatment groups included ablation (MWA), microbubbles with (MBs + MWA), (Flash and MBs phosphate-buffered saline PBS MWA). Hemostasis time, blood tests, ultrasound, pathological inspections, analysis conducted. The Flash MWA group...
Understanding and steering the stability of earth‐abundant electrocatalysts in acidic medium is essential for proton exchange membrane (PEM) water electrolyzer. Manganese oxide (MnO2) one promising candidates oxygen evolution reaction (OER), but it still suffers from overoxidation underlying mechanism remains elusive. Here, we observed that lattice was involved OER process on γ‐MnO2 via Mars‐van‐Krevelen mechanism. Combined with theoretical calculation, revealed release lowers energy barrier...
With the prevalence of smart devices, such as phones, wearable equipments, and infrastructures, location-based service (LBS) has thrived in our daily life. In those practical LBS applications, group detection tracking is a context-related research field many scenarios, school yard, office building, shopping mall so on. this paper, we heuristically develop temporal-spatial method for clustering locating groups, then leverage CRF-based event mechanism to improve performance recognizing...
This paper will introduce two basic switching cells, P-cell and N-cell, along with their implications applications in power electronic circuits. The concept of cells circuits started the late 1970's. presented this have one element (transistor) diode. is mirror circuit N-cell vice-versa, suggests that (1) most can be analyzed re-constructed using these (2) single, dual, 6-pack modules should configured laid-out according to not necessarily conventional way used by industry, (3) many benefits...
This paper proposes a novel packaging method for power electronics modules based on the concepts of P-cell and N-cell. It can reduce stray inductance in current commutation path phase-leg module hence improve switching behavior. Two IGBT modules, specifically N-cell conventional are designed. Using Ansoft Q3D Extractor, electromagnetic simulation is carried out to extract from two modules. Switching behavior with different package parasitics studied Saber simulation. prototype designs...
MRI-based electrical properties tomography, a noninvasive technique for characterizing conductivity and permittivity of human tissues, has been developed the diagnosis cancer specific absorption rate quantification since 1991, based on distortion radio frequency magnetic field in MRI. For high-contrast volume integral equation (VIE) method is appropriate to reconstruct because its flexibility handling complex inhomogeneous scatterers without approximations. In this paper, variational Born...
To develop a more robust desulfur adsorbent to be used for removing thiophenes from fuel oils, complex adsorbent, SBA-15/Cu(I), was prepared using SBA-15 as the substrate of CuCl. The two-dimensional ordered structure remained in such proven by examinations with XRD, SEM, and TEM analyses N2 adsorption at 77 K. Three simulated oils were represent different types oil respect content aromatic components: ALO, aliphatic oil, n-octane; ARO, benzene; LRO, mixture, mixture composed 80 wt %...
In hybrid electric vehicles (HEV), a battery-powered three-phase inverter is used to drive the traction motor. Due switching behavior of this inverter, significant harmonic currents are present on DC side inverter. Traditionally, bulky capacitor filter these harmonics. paper, an active filtering method evaluated substitute for bus capacitor. The power (APF), composed electronic switches and inductor, works as current-source operation principle proposed described implemented in...
This paper introduces the concepts of two basic switching cells, P-cell and N-cell, along with their implications in power electronic circuits. The cells exist almost every circuit. To take advantage these structures, this proposes a novel packaging method for electronics modules. proposed uses as unit module, instead traditional anti-parallel connection active switch diode. rearrangement can reduce stray inductance current commutation pass; therefore, performance reliability device module...
