WebThe high-speed rail power topology developed by Alstom [82] is shown in Fig. 9.43 for use with the 15 kV, 16.67 Hz AC power line. Eight cascaded 6.5 kV IGBT modules are used on the line side to convert the 16.67 Hz input frequency to 5 kHz. This reduces the size and weight of the transformer while keeping the switching power losses at a ... The majority of modern electrification systems take AC energy from a power grid that is delivered to a locomotive, and within the locomotive, transformed and rectified to a lower DC voltage in preparation for use by traction motors.
