Phase Shift Angle Segmentation Modulation for Soft-Switching Medium-Voltage DAB Converter With Series-Connected SiC MOSFETs
Chengmin Li, Rui Lu, Heng Fang
The medium-voltage (MV) dual active bridge (DAB) converter with series-connected SiC (S-SiC) MOSFETs is a promising solution for high-power-density isolated dc/dc converter. To improve the voltage sharing and reliability of S-SiC, relatively large snubber ...
Ieee-Inst Electrical Electronics Engineers Inc2024Analysis and Design for Medium Voltage Dual Active Bridge Converter Based on Series-Connected SiC MOSFETs
Chengmin Li, Rui Lu, Heng Fang
In this article, a series-connected SiC MOSFETs-based medium voltage (MV) dual active bridge (DAB) converter featuring a lowvoltage difference amongdevices and high efficiency is proposed. In the developed DAB converter, the zero voltage switching-on chara ...
Piscataway2023Nanoplasma-enabled picosecond switches for ultrafast electronics
Elison de Nazareth Matioli, Armin Jafari, Palliyage Srilak Nirmana Perera, Minghua Zhu, Giovanni Santoruvo
The broad applications of ultrawide-band signals and terahertz waves in quantum measurements, imaging and sensing techniques, advanced biological treatments, and very-high-data-rate communications have drawn extensive attention to ultrafast electronics. In ...
2020Origin of apparent light-enhanced and negative capacitance in perovskite solar cells
Wolfgang Richard Tress, Ulf Anders Hagfeldt, Firouzeh Ebadi Garjan
So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling peculiarities arising from the mixed ionic-electronic conductivity of this c ...
Springer2019Vacuum circuit breaker modelling for the assessment of transient recovery voltages: Application to various network configurations
Mario Paolone, Carlo Alberto Nucci
Vacuum circuit breakers (VCBs) are widely used for medium voltage applications when low maintenance, long operating life, and large number of allowable switching cycles are required. The accurate estimation of the transient recovery voltages (TRVs) associa ...
Elsevier2018An electromagnetic actuator
Herbert Shea, Juan José Zarate
The present invention concerns an electromagnetic actuator (2) for a haptic display (1). The actuator (2) comprises: a) a first, movable permanent magnetic element (5), the first magnetic element (5) comprising a first latching layer facing side, a second ...
2018Poly-Phased Matrix Converter - A 27 input phases to 3 output phases experimental set-up running with hard and soft commutations
This paper presents an experimental set-up of a 27 phases input to 3 phases output Poly-Phased Matrix Converter (27x3 PPMC) realised for the real time experimentation of the dedicated control electronics. When the original converter system is dedicated to ...
Ieee2011Substrate current modeling for high-voltage smart power BCD technology
Maher Kayal, François Krummenacher, Marc Pastre, Fabrizio Lo Conte
This paper presents a compact- and a macro-model for estimating and simulating the perturbations induced in the substrate by high-voltage transistors switching inductive loads. On one hand, it allows the designer to predict the amount of switching noise ge ...
