An Ultralow Loss Inductorless $dv/dt$ Filter Concept for Medium-Power Voltage Source Motor Drive Converters With SiC Devices
Erik Velander,Georg Bohlin,Åsa Sandberg,Thomas Wiik,Fredrik Botling,Martin Lindahl,Giovanni Zanuso,Hans-Peter Nee +7 more
TL;DR: In this paper, the authors proposed a filter model for the selection of filter component values for a certain $dv/dt$ requirement, where the stray inductance between the power device and the converter output was used as a filter component in combination with an RC-link.
Journal ArticleDOI
An IGBT Turn-ON Concept Offering Low Losses Under Motor Drive dv/dt Constraints Based on Diode Current Adaption
TL;DR: In this paper, a low-loss turn-on concept for the silicon insulated-gate bipolar transistor (Si-IGBT) in combination with silicon p-i-n diode is presented.
Proceedings ArticleDOI
Analysis of short circuit type II and III of high voltage SiC MOSFETs with fast current source gate drive principle
Erik Velander,Lennart Kruse,Stephan Meier,Andreas Lofgren,Thomas Wiik,Hans-Peter Nee,Diane-Perle Sadik +6 more
TL;DR: In this paper, a new short circuit protection scheme based on a universal current-source GD principle without dedicated hardware components was proposed for SC in the dc-link loop under load conditions, called type II and type III.
Proceedings ArticleDOI
Novel Solutions for suppressing Parasitic Turn-on behaviour on Lateral Vertical JFETs
TL;DR: Three different novel solutions to suppress parasitic turn-on for a module design on the gate-drive-unit level are presented and it is shown that the losses could be significantly decreased by active current sources and the proposed clamping solution.
Proceedings ArticleDOI
Silicon Carbide MOSFET Traction Inverter Operated in the Stockholm Metro System Demonstrating Customer Values
TL;DR: In this article, the first time results are reported in literature of a successful test using a silicon carbide (SiC) metal-oxide-semiconductor (MOSFET) traction inverter operated in the Stockholm metro system.
