轻轨车的车内设备要求提供稳定的 DC低压电流。提供该低压电流的辅助电源应不受牵引电流波动的影响 ,必须和中压对地电位分开。通常是 60 0～750 V直流 ,但实际的线电压在 40 0～ 1 0 0 0 V之间波动。Transtechnik的 Combiverter公司采用在高于2 0 k Hz的频率下工作的固定的功
In-vehicle equipment for light rail cars requires a stable DC low-voltage current. The auxiliary power supply to provide this low-voltage current should not be affected by the pulsating current fluctuations and must be separated from the medium voltage to ground potential. Usually 60 0 ~ 750 V DC, but the actual line voltage fluctuates between 40 0 ~ 1 0 0 V. Combiverter from Transtechnik uses fixed work at frequencies above 20 k Hz
