The official premiere of Newag’s new vehicle – Impuls 36WEh, equipped with Medcom’s power electronics – took place at this year’s TRAKO International Railway Fair. The new Impuls is a three-car articulated multiple unit which may function as an electric train (powered from the traction power network with the use of a pantograph) or as a diesel train, which enables it to drive on sections of the route where there is no overhead contact line. The vehicle has a holding capacity of about 330 passengers and can move at a speed of up to 160 kph.
“Newag’s latest multiple unit is the first Polish electric- and diesel-powered hybrid train equipped with our power electronics, intended for passenger transport. It is a very important vehicle, as it may be used on railway sections with no overhead contact line. The new Impuls is also the first major step towards creating an electric- and hydrogen-powered hybrid. We already have such experience. Thanks to our propulsion system using hydrogen fuel cells, trolleybuses in Riga are able to cover a distance of up to 100 km without a traction network. A similar solution of ours was also used in the Solaris Urbino 12 hydrogen bus presented at the UITP Summit in Stockholm. Medcom has a technology which makes it possible to manufacture completely zero-emission and eco-friendly public transport vehicles in Poland,” says Piotr Wroński, Member of the Board at Medcom.
The new EMU was equipped with Medcom’s traction inverters, auxiliary converters, battery chargers, train control and monitoring system (TCMS), and low-voltage power distribution units. Its modern propulsion system consists of two traction containers intended for controlling the operation of asynchronous traction motors (400 kW each) and generating voltage for the supply of the vehicle’s on-board systems. In each container, there is the FT-800-3000 traction inverter, the PSM-82 auxiliary converter, and a converter cooling system manufactured by Medcom.
“We designed and manufactured a state-of-the-art propulsion system making it possible to obtain high performance and reliability parameters in the vehicle. It enables savings and recovery of the energy generated during braking by returning the energy back to the overhead contact line. The entire solution, along with the developed vehicle control, contributes to lower energy consumption, and ultimately lowers vehicle operating costs,” says Joanna Nichthauser, Marketing Director at Medcom.
