An example of vertical solution implementation through partnership is described in this presentation using rail applications. ŠKODA ELECTRIC and HITACHI ENERGY collaborate on applying high-voltage IGBT semiconductors in various module platforms, including newest LinPak IGBT modules for serial usage in traction converters with a 3 kV DC power supply system. In recent years, the ŠKODA GROUP has been intensively developing hybrid dual-system trains with battery drive for a range of 80-120 km on non-electrified lines. A necessary condition for BEMU is the development of a high-tech DC-DC converter with galvanic isolation of 10 kV and a continuous power of 800 kW. Given the weight of LTO batteries, emphasis was placed on minimum weight and installation dimensions and high efficiency of the converter. This clearly leads to the choice to adopt on power semiconductor side SiC technology both on the 800 V traction battery side and on the 3 kV DC traction converter side. Therefore, the partnership with Hitachi Energy was used to develop a SiC module for a voltage of 3.3 kV with an insulation voltage of 10.2 kV. The development of this semiconductor took place in parallel with the development at ŠKODA ELECTRIC converter development over the last couple of years, leading to the stage that as of today 4 BEMU trains are in operation on Czech Railways and these SiC based semiconductors work absolutely reliably, and were the key enabler for this new train platform. As a further step into performance of this train platform, based on the experience with another SiC Powermodule, the RoadPak SiC, for electric buses, there is now the development of a traction inverter for BEMU trains with these SiC modules with parameters of 1200V and the record current of 1150A for powering asynchronous traction motors with a continuous power of 340 kW. The development of power SiC modules and their application in railways allows to come up with ecological solutions for modern trains and significantly reduce the environmental burden and increase the comfort of passengers on the railway. European cooperation between two major companies is a best practice example of this.
