These inverters convert incoming DC power to AC power as well as control the amount of power (voltage and frequency) being supplied in accordance with the train’s speed, etc. In addition, these inverters are also capable of regenerating power from the motors as the train decelerates.
This paper described the advantages of traction inverter systems with LV100 full-SiC power modules for railway vehicles and their application to the Odakyu 5000 series. As manufacturers around the world must contribute to the SDGs, railway systems that have less environmental impact and that help save energy will play an important role.
Assuming systems for conventional lines in Japan, one traction inverter system drives four induction motors of up to 220 kW connected in parallel as the specifications. A traction inverter system consists of a line breaker circuit, power unit, and gate control unit. The LV100 SiC power module enables the cooler to be compact and the
As shown in Fig. 3, as the main circuit system, one variable voltage variable frequency (VVVF) traction inverter system controls four main motors. Figure 4 shows the appearance of a VVVF traction inverter system.
