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 ...

Origin 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 ...

Vacuum 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 ...

Substrate 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 ...
