Rail Transit

Core definition: Key electrical equipment in rail transit (such as high-speed railways, subways, and electric drive trains), it serves as the "energy conversion hub" connecting the power supply system and the traction motor.Core function: Co…

Main function: Convert the fluctuating DC grid voltage into constant voltage and constant frequency three-phase AC power to provide power for auxiliary electrical equipment. Electrical isolation between high-voltage and low-voltage electrical equipmen…

Core definition: An intelligent management system that monitors key data (such as voltage, current, power, energy consumption, etc.) in real time during the processes of energy generation, transmission, and consumption, and feeds the data back to the …

Core definition: A modular electronic component integrating power semiconductor devices (such as IGBT, MOSFET), drive circuits, protection circuits and heat dissipation structures, used to efficiently achieve the conversion, control and transmission o…
