The 14th edition of the InnoTrans trade fair, Europe’s largest public transportation event, will take place on September 24-27. This year in Berlin, we will present our latest energy-saving solutions for all types of rail vehicles as well as electric and hydrogen-powered buses. All are based on silicon carbide (SiC) technology. We encourage you to meet our team at booth 255 in building 17. If you need an admission ticket to the fair, please contact us at marketing@medcom.com.pl.
Medcom has been developing technologies to optimize the energy consumption for 36 years, including the innovative solutions for public transportation, based on silicon carbide, for more than 10 years. We started serial production of SiC drive systems as early as in 2018. Since then - based on silicon carbide technology - we have already delivered several thousand converters that have been used in the energy-efficient electric and hydrogen buses, trolleybuses, trams, subway trains, passenger carriages, EMUs, and locomotives. Their use in public transport vehicles ensures extremely high efficiency and thus low energy consumption with much lighter weight and dimensions of the equipment.
“Medcom has probably the longest experience with silicon carbide technology among the world’s manufacturers of power electronic equipment, and vehicles with our devices are currently on the roads and tracks in more than forty countries on six continents. They already correspond to half of our sales, and we plan to increase this share to 70-80 percent in the next few years,” says Joanna Nichthauser, Medcom’s director of marketing communications. “Some leading power electronic equipment manufacturers say that the silicon carbide technology has yet to be proven and are still testing it. Our SiC equipment has been used in all types of public transport vehicles for several years now, and in each case they provide higher energy efficiency and lower operating costs. In addition, because they are smaller and lighter than traditional components, they give designers far greater flexibility in vehicle design,” she adds.
Medcom’s energy-efficient solutions are installed in more than a thousand public transportation vehicles around the world each year. Some of them will be presented on September 24-27 at InnoTrans in Berlin. Four categories of equipment will be on display at our booth (booth 255, building 17):
Battery chargers for rail vehicles, based on the silicon carbide technology, are used in diesel and electric multiple units, locomotives, passenger carriages, subway trains, and trams. Also on display at the Medcom booth will be a battery charger for the passenger carriage platform designed for Siemens Mobility US, which is part of the EEB (Electric Equipment Box) device that powers passenger carriages and recharges emergency power batteries. Carriages equipped with this solution are currently in operation in Canada and in the US.
Fuel cell converters in the SiC technology are used in electric multiple units, as well as in Solaris Urbino nE12 H2 and nE18 H2 hydrogen-powered buses. The Solaris Urbino 18 hydrogen-powered bus with a Medcom propulsion system has been named Bus of the Year 2025 by the Jury of the International Bus of the Year contest. It is the first hydrogen-powered bus to have received this award.
A propulsion and energy recovery system for trams, made with SiC technology has been used in, among others, Hyundai Rotem trams manufactured for Warsaw, which made it possible to achieve extremely high energy efficiency performance. A detailed analysis of data, obtained from the operation of the vehicles in real conditions for over a 12-month period, showed that trams with Medcom power electronics consume almost 40% less energy than the vehicles used by Warsaw Trams to date.
Auxiliary converters with the SiC technology are used, among others, in subway trains and passenger carriages for high-speed trains. They are the first application of the silicon carbide technology in high-speed trains in Europe, and are a completely new Medcom design that sets the highest standard for efficiency and size of the multisystem converters.
In addition, vehicles equipped with Medcom power electronics will be displayed in the outdoor exhibition area:
GRIFFIN E4MSUa is the latest Polish multisystem electric locomotive that has reached a speed of 240 km/h during test runs! The SiC technology inverters and converters from Medcom that the vehicle is equipped with, are not only energy efficient, but have also been optimized in terms of weight. This is what, among other things, makes the locomotive the lightest in its class.
The Z1B type carriage presented at Innotrans is the first result of the work carried out by FPS H. Cegielski for PKP Intercity. It is equipped with a multi-system carriage converter and an event recorder from Medcom.

“We warmly invite you to visit our booth at Innotrans. This is a great opportunity not only to learn about our latest energy-efficient solutions for public transportation, but also to talk to our engineers. We will be happy to tell you about our latest solutions and implementations,” invites Joanna Nichthauser.
