Research direction:
Our group research on coupling relationships in high-speed train, and focus on vehicle-network relationship. There are two basic research parts.
The first is traction drive system, as shown below. In it, 4-quadrant rectifier is the key point. We research current harmonics, harmonic influencing factors, resonance oscillation and stability range.
The second is tractive power supply system. We care about its characteristics.
The coupling relationship between vehicles and network is also the main point of our research.
In addition to the common experimental platform, we also have a semi-physical platform for convenience of research.
Personnel composition:
At present, we have one doctoral student, Shihui Liu, and 4 master students, Meijun Mu, Renzhe Zhang, Meng Jia and Xiao Deng, in our research group.
