The full SiC technology
MEDCOM is one of the few companies in the world which are trying to promote the SiC technology, thanks to which within the coming years, we might be facing a huge technological change in the market and progress in the design of power electronics for public transport (rail, metro, trams, electric buses, trolleybuses).
Instead of the standard silicon semiconductors, the SiC technology uses silicon carbide ones.
- electrical energy converters in vehicles lighter by 30-40%
- the size of these devices smaller by 30-40%
- significantly lower noise level and higher level of comfort for the passengers
- better vehicle driving parameters
- energy losses lowered by 30%
The first product based on components made of silicon carbide was presented by MEDCOM in 2014. It was the PSM-35 SiC auxiliary converter. In 2016, MEDCOM’s product offering was enriched by a traction inverter integrated with an auxiliary converter, and battery charging systems for e-buses which was made using the full SiC technology.
Currently, another product based on the SiC technology is under development – a multi-system drive and power supply system for electric multiple units (EMUs). The project is co-funded from the resources of the INNOTABOR programme and is expected to be completed in three years.
