Multilevel converters and inverters have become the enabling power conversion technology
for high voltage high power applications in today's power systems and large motor drives …

This paper presents a new configuration of a main traction converter with a medium-
frequency transformer (MFT) using matrix converters intended for locomotives and …

With the new generation of full low floor passenger trains, the constraints of weight and size
on the traction transformer are becoming stronger. The ultimate target weight for the …

This paper presents a novel single-stage ac/dc rectifier with high-frequency isolation and
bidirectional power flow capability, which is feasible to connect dc grids to ac ones. A …

In ac-supplied traction systems (eg, 15 kV, 16.7 Hz), the energy supplied by a conventional
transformer results in large volume, high weight, and relatively low efficiency. In this paper …

An isolated ac-dc converter topology includes a capacitively snubbered voltage source
converter (VSC) and a cycloconverter, coupled by a medium frequency transformer. The …

This dissertation is the result of the research and development of a power conditioning
system for superconductive magnetic energy storage systems (SMES). The dominant …

A configurable converter topology is presented as front-end converter for a locomotive that
can be operated as well on a high voltage AC-system as on a medium voltage DC-system …

This paper describes an ac/dc converter system consisting of a voltage-source converter
(VSC) with purely capacitive snubbers and a two-phase by three-phase cycloconverter …

This paper focuses on the controller design based on symmetrical optimum and extended
symmetrical optimum methods for a single-phase AC/DC converter system employing …
