The paper presents the concept of advanced and highly integrated IGBT propulsion and an auxiliary power supply converter for diesel electric multiple unit. The incoming power from the diesel-generator group is transformed into traction power by the propulsion converter. The auxiliary power supply converter supplies energy to the on board network and the vehicle battery directly from the same DC‑link. Energy recuperated during braking is fed back into the DC-link, where it may be consumed by the auxiliary systems, or dissipated into heat by the braking chopper. All propulsion and auxiliary supply equipment as well as cooling system are integrated into a roof-mounted converter box, while a high degree of functional integration as well as the maintenance cost optimized design are realized. The increased power density of the new generation converters enables compact and light-weighted vehicle designs.
