Emission-free transport

Let’s fight for the climate together

In 2050, the European Union will become climate neutral and the public transport will be free freed from fossil fuels and will be powered exclusively by the green energy.

The transformation of the European transport is a challenge that can only be met by the joint effort of all the participants in our market – European cities, operators, vehicle and component manufacturers, with the participation of the entire energy sector.

Medcom’s energy-saving solutions already serve over 1,000 new public transport vehicles around the world each year. Our technologies are used by leading manufacturers of EMUs, electric and hydrogen buses, metro cars, trams, passenger coaches, and trolleybuses.

Energy at a premium

Energy efficient mobility is a standard,
not a novelty

The transformation of public transport requires equally dynamic changes in the energy sector. We need new, alternative sources of clean energy to compensate for its deficit, as well as the solutions that will make vehicles even more economic in everyday use.

For over 35 years, Medcom has been developing technologies that reduce energy losses and optimise energy consumption. Medcom’s energy-saving propulsion inverters, combined with a regeneration system, allow to reduce the energy demand of vehicles by up to 30%.

We have the knowledge of how to save the energy and we have created the technological solutions enabling us  to achieve even the most challenging climate and environmental goals.

Our baSiC

The silicon carbide technology is our standard

Medcom has been implementing the silicon carbide technology in its designs for many years. We started serial production of SiC propulsion systems as early as in 2018. Today we are able to use silicon carbide components in all types of public transportation vehicles.

We have already installed more than 25,000 SiC power modules in our converters. They are used in electric buses, trams, metro cars, passenger coaches, EMUs, and locomotives. In each case, silicon carbide provides higher efficiency while giving car builders greater design flexibility due to the smaller size and lower weight of the devices.

Therefore, in our offer, the SiC technology is no longer a special option – it is our ”baSiC”.

Benefits:

Up to 30% lower operating costs of vehicles in urban traffic

Up to 2.5 months of free use of the vehicle a year

Extremely high efficiency of power electronics

30%–45% lower weight and dimensions of devices

Greater range and longer battery life

Energy regeneration and storage

Vehicles are a source of clean energy

Saving energy in transport is a necessity dictated both by a concern for the future of our planet and a purely economic calculation. Medcom regeneration systems allow to recover energy from braking and to reuse it many times while driving. Each vehicle equipped with an on-board energy storage device becomes a source of free, low-emission renewable energy.

We used the first energy recovery system for traction vehicles in 2013. The latest generations of our devices are widely used in trams, trolleybuses, and also in electric buses and electric & diesel multiple units.

Benefits:

Up to 70% energy recovered during braking

Possibility to operate on non-electrified sections

Possibility of emergency drive in case of the catenary power loss

Lower operating costs of vehicles in urban traffic

Energy-efficient propulsion systems

The heart of a vehicle in SiC technology

Medcom’s propulsion inverters and auxiliary converters are commonly used in all types of rail vehicles worldwide, as well as in electric buses, hydrogen powered vehicles and trolleybuses.

We support a sustainable public transport by offering products which not only use the latest generation of IGBT transistors, but also a wide range of the energy-efficient and highly competitive solutions in the silicon carbide technology (SiC).

Our projects

123 Hyundai Rotem trams for Warsaw

Even 40% energy savings thanks to the SiC technology and supercapacitors

One of the key criteria in the tender for the purchase of the newest trams for Warsaw was the energy efficiency. We designed a solution that allowed to reduce energy consumption by 30% compared to the older generation of trams. The above-average parameters were confirmed during the tests carried out by the operator in the city traffic.

24 kilometres without catenary power supply

thanks to an onboard energy storage unit

In 2014 in San Diego, a light rail vehicle Siemens S70 set a Guiness record at the distance covered by a battery powered LRV. A similar solution was implemented by Medcom also in Siemens Mobility USA LRVs for North Carolina, and in Lajkonik trams produced for Cracow.

Electric buses by Solaris

2 months of free driving a year thanks to the SiC technology

Since 2014 we have introduced a range of EV systems consisting of propulsion inverters and auxiliary power supply. Based on the experience with IGBT technology, we have developed full SiC propulsion inverters to reduce energy consumption of a new generation of EV. Urbino Electric buses made by Solaris operate all over Europe. In order to extend the eBus family by hydrogen buses, we have designed fuel cell energy converter operating as a link between the fuel cell and the propulsion system.

Impuls EMU by Newag

Impuls is an EMU platform by Polish company Newag, ranging from 2 to 6 cars. It is designed to operate in 3 kV catenary system. We have designed a range of propulsion inverters and auxiliary power supply, as well as TCMS, to meet the requirements of different end-users. We have supported Newag to introduce a hybrid version of Impuls which can be supplied either from catenary or diesel motors. Recently, we have developed a new supercapacitor regeneration system for even more energy efficient addition to Impuls family.

Multi-System Dragon 2 locomotive by Newag

Reduction of energy losses

We supplied propulsion and auxiliary power supply systems to a six-axle cargo locomotive made by Polish car builder Newag. The E6MST Dragon 2 is designed to operate in 3 kV DC and 25 kV 50 Hz AC catenary systems. Dragon 2 is equipped with an auxiliary power supply in SiC technology.

37 metro trains of Škoda Varsovia

The newest Škoda vehicles will soon enter commercial operation. Medcom supplied them with a highly-efficient propulsion system and a state-of-the-art power supply system. Auxiliary power supply produced by Medcom is also used in the Siemens Inspiro metro trains in Warsaw.

Solaris Trollino hydrogen trolleybuses for Riga

100 kilometres without catenary power supply

Latvian hydrogen trolleybuses is a wolrd-unique solution. Medcom’s propulsion system used in those vehicles, together with an energy storage unit and a fuel cell, reduces the usage of hydrogen, and at the same time guarantees a proper operation of the propulsion system in all operational conditions.

Swing trams by Pesa

Swing family is the largest series of trams equipped with Medcom power electronics. For over 10 years we have been providing Polish car builder Pesa with propulsion inverters and auxiliary power supply for next generations of a Swing tram. Today, over 900 Swing, Twist, Foxtrot, Jazz and Jazz Duo trams are serving passengers in 10 different cities in Central Europe.

Battery Chargers for eBuses

As electric vehicles (EV) become one of the key parts of urban transport, investments in charging infrastructure are critical to maintain the fleet operation. Medcom has developed a range of EV chargers -from 30 kW mobile chargers used in depots, up to 650 kW fast pantograph chargers. Our key goal was to offer the highest efficiency of energy conversion. Utilization of SiC technology on board of an eBus and in chargers, helps in reducing the total electricity consumption and fleet costs.

SiC propulsion systems for eBuses

They lower the energy consumption by 20%

Replacing silicon with SiC-based components allows to reduce the energy consumption in urban traffic. The solution developed by Medcom is successfully used in the electric buses produced by Solaris, including those vehicles dedicated to operate on the suburban bus lines.

Solaris Urbino 18 hydrogen – Bus of the Year 2025

The Solaris Urbino 18 hydrogen stands out with its cutting-edge hydrogen technology, which allows it to travel up to 600 kilometres on a single refuelling without any emissions – making it a sustainable and efficient solution for modern public transport. The vehicle, equipped with propulsion system with silicon carbide (SiC) technology from Medcom, has been awarded the prestigious Bus of the Year 2025 title by the International Jury of the Bus of the Year.
