1 C 1 M PROPULSION CONTROL SYSTEM OF HIGH SPEED TRAIN FOR INDIVISUAL TRACTIVE EFFORT CONTROL

摘要

A 1C1M propulsion control device for a high speed train for individual motor output control is provided. The propulsion control device for a high speed train in which two traction motors are mounted on one car comprises: a first converter which converts alternating current voltage into direct current voltage to drive a first traction motor; a second converter which is connected to the first converter in parallel, and converts alternating current voltage into direct current voltage to drive a second traction motor; a single direct current link terminal which charges the direct current voltage converted by the first converter and the second converter; a first inverter which converts the direct current voltage charged in the single direct current link terminal into the alternating current voltage and controls the first traction motor at a first frequency; and a second inverter which is connected to the first inverter in parallel, converts the direct current voltage charged in the single direct current link terminal into alternating current voltage, and controls the second traction motor at a second frequency. Accordingly, it is possible to control a diameter between rotating wheels to be equal to or less than 40 mm, and it is possible to perform precise slip/slide control.
