Premium PSU was present at the latest edition of InnoTrans 2022.
After four years without being able to attend due to the pandemic, Premium PSU took the opportunity to present innovative solutions in power electronics for the railway industry.
The company has been focusing on providing solutions of higher power to the industry and new alternatives for efficient power supplies. A clear example is a new 40kW DC/AC inverter, which stands out for having two outputs, one of 35kW and the other of 5kW, where two loads can be controlled independently.
On rail trams, this inverter manages the HVAC system of the train and the HVAC system of the passenger cars. Its CANBUS communication port controls all the parameters of the unit, although it is interesting to note that the frequency and output voltage are controlled independently. Despite being very robust and powerful, the unit weighs only 60kg and is presented in a compact design. The inverter also includes an innovative active catenary filter that protects itself against surges on the catenary.
During European Mobility Week (17 September), GTT Group in collaboration with Hitachi Rail, presented a new electric motor tram in Turin, which will be in operation in winter 2022. All cars include Premium PSU’s 40kW three-phase inverter in the ventilation system, which was custom-designed and manufactured according to the needs of the project.
For 2023, Premium PSU is planning to expand its standard product range with new designs: a bidirectional converter and two models of variable frequency drives, being the first power engineering company to offer VFDs specifically designed for the railway market in their portfolio.
