Based on experience in designing and manufacturing AC and DC power supply systems, APS Energia has developed and implemented devices for traction vehicles. With the continuous growth in the potential of eco-friendly transportation, the development of products for this sector through the R&D department remains one of the company’s strategic directions.

Public transportation is an essential element in the development of modern infrastructure. This trend drives the growth of rail fleet, railway line modernizations, and the construction of roads and highways. In recent times, electric vehicles are increasingly being introduced on a larger scale in Poland. APS Energia SA, with its experience in designing and manufacturing AC and DC power supply systems, has developed and implemented converters for traction vehicles.


APS Energia SA devices are designed by highly qualified engineers. Our devices undergo thorough testing, resulting in their high quality and reliability. Appropriately designed and reinforced enclosure structures are made from high-quality materials. Adequately selected electronic, electrical, and mechanical components ensure the high quality and resistance to challenging operating conditions.


APS Energia’s offer includes devices for T&T such as parameter recorders, diagnostic and control systems (TCMS), static converters, voltage regulators, buffer power supplies, and inverters installed in vehicles produced for both the Polish and foreign markets.

For years, we have been collaborating with manufacturers of new and modernized rail and bus fleets in Poland, including H. Cegielski – Fabryka Pojazdów Szynowych sp. z o.o., Pojazdy Szynowe PESA Bydgoszcz S.A., PESA Mińsk Mazowiecki S.A., NEWAG S.A., Stadler Polska sp. z o.o., PKP Intercity Remtrak sp. z o.o., Seluch sp. z o.o., Serwis Pojazdów Szynowych sp. z o.o., Public Transport Service sp. z o.o., Saatz sp. z o.o., ARP E-Vehicles sp. z o.o., and with subsystem suppliers for these vehicles, including FOGO sp. z o.o., EPS System sp. z o.o., ZPAS S.A. Another area of our activity involves cooperation with companies providing vehicle design services, such as VIS Systems sp. z o.o., RTS Engineering sp. z o.o., and TechSolutions Group sp. z o.o. Additionally, we collaborate with scientific institutions, such as the Railway Institute, PIT Tabor, and CTO.


A new and dynamically developing project at APS Energia is the construction of a traction converter for a railway vehicle along with its entire auxiliary equipment (TCMS, braking resistor, static converter, line reactor, buffer power supplies, switchgear, and anti-slip control system).


The production of our devices at APS Energia is organized following the highest quality standards, certified by ISO 9001 and ISO/TS 22163.
