轨道交通 Rail Transit

牵引变流器是轨道交通车辆的动力心脏，负责将电网的电力转换为驱动电机的电能。这是一个典型的超高压、大功率应用场景，对功率器件的耐压和效率要求极高。氧化镓正是为此而生。在高铁牵引供电、电力机车牵引等场景中，基于氧化镓的“超级开关”等功率器件，有望取代传统的硅基模块，大幅提升能源转换效率，并显著减小设备的体积和重量。

The traction converter is the beating heart of a rail transit vehicle, responsible for converting electricity from the grid into power for the traction motors. This is a typical ultra-high-voltage, high-power application that places extreme demands on the voltage blocking capability and efficiency of power devices. β-Ga₂O₃ is born for exactly this. In scenarios such as high-speed rail traction power supply and electric locomotive traction, β-Ga₂O₃-based "super switches" and other power devices are expected to replace conventional silicon-based modules, dramatically improving energy conversion efficiency while significantly reducing equipment size and weight.
