Volume and weight of the propulsion equipment of a traction drive are most important features to provide more efficient transportation in the future. It will be shown how the converter technology for traction drives has improved its performance in the past decades and new developments are presented promising a further increase in power density. The machine and corresponding gear and suspension system is even more weight sensitive, and latest measures to increase the performance will be presented.

The paper discusses design and development problems of auxiliary power supplies (APS) with output powers up to 100 kW to be used in 3.0 kV DC commuter trains. Focus is on the implementation of 6.5 kV IGBTs in IHVM of APS. Using single 6.5 kV IGBT module instead of several series-connected IGBTs or even converters helps to achieve more reliable, efficient, compact and lightweight design than ever. For the APS with output power up to 100 kW, the simple half-bridge topology and two 200 A 6.5 kV IGBTs (one for the TOP and one for the BOT switch) it is sufficient to fulfill all the design requirements. Given paper generally deals with topology selection, analysis of switch losses and cooling of HV IGBT as well as with control and protection of the new power supply. Some generalizations and practical considerations are given.

Large inverter-systems are characterized by a significant number of parallel IGBTs operating on the same dc-link. The IGBT-phases are cross coupled by their mutual stray inductance. This paper investigates the special effects occurring due to nearly simultaneous switching of multiple IGBTs. This operation can cause a significant increase in stress on the IGBT and on the free wheel diode. Countermeasures to cope with these problems will be discussed.
