 | Development Of A Two-Level Onix Converter For The 3kvdc Catenary Network.
By A. Colasse, Ch. Delecluse, Th. Lorent | |
|
Abstract: ONIXä is the standard ALSTOM IGBT converter
range for traction applications. This article explains the new
ONIXä development for 3 kV DC catenary network
applications. Up-to-now the realisation of 3 kV DC railway
converter required specific use of low voltage semi-conductor
to sustain the 3 kV voltage. Now it becomes possible to use the
simple 2-level inverter scheme to realise a 3kV converter for
railway traction. This paper will explain the main choices
and original application for the 3 kV traction converter and
the integration in a cubicle.

| | Four Type Input Voltage Static Converter For Suppling Auxiliary Services On Railway Wagons
By Vasile Radulescu, Ioan Strainescu, Leonard Moroianu, Viorica Serbu, Sergiu Gheorghe, Florin Huzlau, Florin Bozas, Emil Tudor, Gheorghe Mitroi, Bogdan Radulescu, | |
|
Abstract: The modernization of the railway wagons for
passengers able to operate the international traffic of European
countries are focused on the static converters for auxiliary
services. Those converters are supplied through an internal link
with four ranges of voltage: 1500 Vac, 50Hz; 1000 Vac, 16 2/3
Hz; 1500 Vdc; 3000 Vdc.
The outputs of such converters usually are:
1) 28 Vdc for accumulators and control equipment, with
respect for temperature range, charging current
(70…100Adc) and overall current(200…250Adc);
2) 3x400Vac, 2…50 Hz, 15…30 kVA for induction motor of
air conditioning systems;
3) 3x400Vac, 50 Hz, 10…45 kVA for heating resistors;
4) 230 Vac, 50 Hz for various devices as fans, water heaters,
dust cleaners, coffee filters, shavers, laptops. 5) ICPE SAERP has designed and produces 18 of such high
complexity converters. Only a few European companies
are able to produce such converters. The conception of our
technical diagrams and solutions is new, modern and
patented (The paper will describe them). The control, the
regulations and diagnose of the converters are performed
by microprocessor control units, and the inverters are
based on IGBT transistors.

| | New IGBT Traction Converter For Multi-System Locomotives And Power Heads
By Ingo Herbst, Stefan Umbricht | |
|
Abstract: A new multi-system traction converter with 6.5kV IGBT
for Bombardier Transportation’s new advanced multi-system loco
is presented with its key features and design criteria. The first
applications of the converter are in a new multi-system locomotive
for the SBB and a power head for Renfe.

| | Review Of Possible Dc-Dc Converter Topologies For Trams Auxiliary Power Supply
By Dmitri Vinnikov, Tonu Lehtla | |
|
Abstract: The paper is devoted to a review of various topologies
of DC-DC auxiliary power supplies for a tram. The main
criteria of design of the auxiliary power supply for railway
traction are given. Some examples of a practical realization of
different topologies are considered.
