We support the technological transformation of strategic sectors of the economy by offering solutions that minimise energy consumption and give our customers a competitive edge. In the spirit of sustainable development, climate neutrality, and responsibility towards future generations.
High energy prices and increasingly restrictive climate neutrality standards place significantly higher demands on vehicle manufacturers and transport companies in terms of energy efficiency. For nearly 40 years, Medcom has been developing technologies that reduce energy consumption and mitigate the negative impact of public transport on the environment.
We know how to effectively reduce energy losses in vehicle propulsion systems, auxiliary power systems and during charging. We also make effective use of the energy recovered during braking.We were one of the first in the world to recognise the potential of silicon carbide technology and then introduce it into series production.
As a result, new vehicles with Medcom SiC power electronics already consume up to 40% less energy.
Rolling stock usage is one of the highest costs in transport operators’ budgets. Thanks to Medcom’s solutions, energy bills become significantly lower.
Wrocław’s Moderus Gamma trams with SiC propulsion systems consume 30% less energy than older MPK Wrocław trams with IGBT propulsion. The combination of SiC power electronics with a supercapacitor energy recovery system increases savings by up to 40%, as exemplified by the 140N trams in Warsaw.
SiC technology and energy recovery systems also bring measurable benefits in the railway sector. The operation of a fleet of 10 hybrid Impuls trains with Medcom power electronics minimises fuel consumption and generates a profit on the order of several million zlotys per year.
We are able to optimise energy consumption in all types of vehicles – not only new ones, but also modernised ones.
The unique knowledge of our engineers, full control over the design and production process, combined with the use of the highest quality components, allows us to offer devices with the highest parameters in terms of reliability and durability.
We are able to design a completely new solution within a few months of starting work, guaranteeing one of the shortest ‘Time to Market’ on the market. We guarantee comprehensive training, technical and service support – at every stage of vehicle production, throughout its entire service life and during necessary upgrades.
The record-low cost of ownership of Medcom devices, above-average reliability and fast and simpler servicing are also the result of access to silicon carbide (SiC) technology.
We use silicon carbide power electronics in all types of public transport vehicles around the world: trams, metro trains, locomotives and passenger carriages, as well as electric buses and trolleybuses. This includes battery, hydrogen and hybrid vehicles, as well as chargers for electric buses and devices for the energy sector, e.g. hybrid inverters.
60% of the products that leave the Medcom factory are devices designed using silicon carbide technology. SiC is our contribution to the development of competitive, modern and energy-efficient public transport.
Up to 30% lower energy consumption costs for vehicles
Extremely high efficiency and reliability of power electronics
Record low LCC (Life Cycle Cost)
Simplified maintenance
Quieter drive operation
Up to 45% lower weight and dimensions of devices
Saving energy in transport is a necessity dictated both by concern for the future of our planet and by purely economic considerations. Medcom recuperation systems recover energy from braking and reuse it multiple times during driving, thus minimising the operating costs of rolling stock and bus fleets.
Every vehicle equipped with our on-board energy storage system becomes a source of free, low-emission renewable energy.
The latest generations of our energy recovery systems are widely used in electric multiple units (EMUs), trams, trolleybuses, and electric and hydrogen buses.
Up to 70% of energy recovered during braking
Lower fleet operating costs
Ability to travel on non-electrified sections
Ability to travel in emergency mode without power from the traction network
The transformation of the energy system and the growing importance of renewable energy sources also require new solutions in transport. This is why V2G technology is so important, as it helps to stabilise the energy system and balance energy from distributed sources such as wind and solar farms.
Two years ago, based on our experience from projects implemented in Japan, we introduced the first chargers in Poland with bidirectional energy flow functionality. Thanks to Medcom’s V2G, every electric vehicle also becomes an energy supplier and an integral part of the energy ecosystem.

Capability of operation with power from multiple traction voltages
The traction converters SFT-3000k-MSU/PSM-175-SiC-MSU, developed and manufactured by MEDCOM, are designed to drive four-axle multi-system electric locomotives of the E4MSUa series and to generate the 3×440 voltage to supply low-voltage circuits of the vehicle. Being a three-system solution, the traction converters SFT-3000k-MSU are adapted to three values of input voltage 3 kV DC, 15 kV AC 16.7 Hz, 25 kV AC 50 Hz.
Reduction of energy losses
Thanks to SiC technology, the latest processors and software, but above all our experience in optimising the mechanical design of converters, we have created a compact product with 96% efficiency. We have reduced the weight of the device by approximately 400 kilograms, reduced the dimensions of the magnetic components several times over, and minimised the cooling system requirements.
Hybrid EMU with an onboard energy storage system
Powered by Medcom’s power electronics, the Impuls 2 is the first hybrid multiple unit in Europe equipped with a supercapacitor-based energy storage system. Newag’s innovative solution makes it possible to accelerate the vehicle up to 50–60 km/h and depart from a station solely using clean, green energy recovered from braking. Medcom supplied the traction system and converters, and developed the energy recovery system working in conjunction with the supercapacitor.
Even 40% energy savings thanks to the SiC technology
The outstanding result in terms of energy efficiency is the effect of combining SiC technology with the supercapacitor-based energy recovery system and the Train Control and Monitoring System (TCMS) designed for energy optimization.
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.
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.
30% lower energy consumption
The new Moderus Gamma trams with SiC-based propulsion systems from Medcom consume up to 30% less energy compared to vehicles with IGBT power electronics in the fleet of the Wrocław operator. For comparative tests over a distance of more than 100,000 kilometers, three different tram models were selected: Moderus Beta (MF24AC), Moderus Beta (MF17AC), and Škoda 16T.
37 metro trains of Škoda Varsovia
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.

Medcom has equipped Solaris Bus & Coach’s Charging Park for battery-powered vehicles with bidirectional chargers based on the Vehicle-to-Grid (V2G) standard. This is the first installation of its kind launched in Poland, but not Medcom’s first V2G charger. We had previously implemented similar projects in Japan.
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.
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.
20% lower energy consumption
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.
For almost 40 years, we have been supporting the technological transformation of strategic sectors of the economy by offering solutions that reduce energy consumption. Our products minimise the negative impact of public transport, energy and industry on the environment, reduce the carbon footprint and promote climate protection.
We are one of the largest independent European manufacturers of power electronics for rail vehicles, electric buses, hydrogen buses and trolleybuses. We were the first to implement energy-efficient drives and devices using silicon carbide technology in series production. And now we use it in all types of public transport vehicles, electric vehicle charging systems and energy storage facilities. SiC is our contribution to the development of an energy-sustainable economy.
