11 11 PROPULSION CONTROL SYSTEM OF HIGH SPEED TRAIN FOR INDIVISUAL TRACTIVE EFFORT CONTROL

摘要

A 1C1M propulsion control system for a high-speed train for controlling individual motor output is provided. The propulsion control apparatus includes a first converter for converting an AC voltage to a DC voltage for driving the first traction motor, a second converter for converting the AC voltage into a DC voltage, A second converter connected in parallel to convert an AC voltage to a DC voltage for driving the second traction motor; a single DC link stage charging a DC voltage converted by the first converter and the second converter; A first inverter connected in parallel with the first inverter for converting a DC voltage charged in a single DC link stage into an AC voltage, And the second inverter controlling the second traction motor at the second frequency, it is possible to control the diameter of the wheel to be rotated to be 40 mm or less, and the precision slip / The de control is possible.
